## Me playing around with colors.

Posted 6 Months ago by chiarizio

Red: Hue = 0 degrees or 360 degrees.
Yellow: Hue = 90 degrees.
Green: Hue = 180 degrees.
Blue: Hue = 270 degrees.

Orange: Hue = 45 degrees.
Chartreuse: Hue = 135 degrees.
Cyan: Hue = 225 degrees.
Magenta: Hue = 315 degrees.

Black: Lightness = 0%.
White: Lightness = 100%.
50% Grey: Lightness = 50%, Saturation = 0%.

25% Grey: Lightness = 25%, Saturation=0%.
75% Grey: lightness = 75%, Saturation = 0%.

So I think I’m planning Adpihi and Reptigan to have up to 85 basic color terms. (Subject to change!)
I’m organizing them by Lightness, Saturation, and Hue.

The first set of 11 colors I’ll call “primary”.
They’ll vary L and S from 0% to 100% as multiples of 50%; and vary H by multiples of 90 degrees from 0 degrees to 360 degrees (but H=0 and H=360 are the same).

If L=0% or L=100% neither S nor H matter.
L=0% is black, and L=100% is white.
If S=0% then H doesn’t matter; the color is on the gray scale.
L=50% S=0% is neutral gray.

There are eight more colors in this set.
L=50% S=100% H=0 degrees or 360 degrees: RED
L=50% S=50% H=0 or 360: RED-GRAY
L=50% S=100% H=90 degrees: YELLOW
L=50% S=50% H=90 degrees: TAN
L=50% S=100% H=180 degrees: GREEN
L=50% S=50% H=180 degrees: GREEN-GRAY
L=50% S=100% H=270 degrees: BLUE
L=50% S=50% H=270 degrees: BLUE-GRAY

The next set of 34 colors, I’ll call “secondary colors”. They come in three subsets.
The first of these subsets contains 18 colors.
Lightness is an odd multiple of 25%. Saturation is still a multiple of 50%. Hue is still a multiple of 90 degrees.
L=75% S=0% H doesn’t matter: LIGHT GRAY
L=25% S=0% H doesn’t matter: DARK GRAY
L=75% S=100% H=0 or 360 degrees: LIGHT RED
L=25% S=100% H=0 or 360: DARK RED
L=75% S=50% H=0 or 360: LIGHT RED-GRAY
L=25% S=50% H=0 or 360: DARK RED-GRAY
L=75% S=100% H=90 degrees: LIGHT YELLOW
L=25% S=100% H=90: DARK YELLOW
L=75% S=50% H=90: LIGHT TAN
L=25% S=50% H=90: DARK TAN
L=75% S=100% H=180 degrees: LIGHT GREEN
L=25% S=100% H=180: DARK GREEN
L=75% S=50% H=180: LIGHT GREEN-GRAY
L=25% S=50% H=180: DARK GREEN-GRAY
L=75% S=100% H=270 degrees: SKY
L=25% S=100% H=270: DARK BLUE
L=75% S=50% H=270: SKY-GRAY
L=25% S=50% H=270: DARK BLUE-GRAY

The next subset contains 8 colors.
Saturation is an odd multiple of 25%. Lightness is still 50%. Hue is still a multiple of 90 degrees.
L=50% S=75% H=0 or 360 degrees: GRAYISH RED
L=50% S=25% H=0 or 360: REDDISH GRAY
L=50% S=75% H=90 degrees: GRAYISH YELLOW
L=50% S=25% H=90: YELLOWISH GRAY
L=50% S=75% H=180 degrees: GRAYISH GREEN
L=50% S=25% H=180: GREENISH GRAY
L=50% S=75% H=270 degrees: GRAYISH BLUE
L=50% S=25% H=270 degrees: BLUISH GRAY

The last subset also has 8 colors.
Hue is an odd multiple of 45 degrees. Lightness is still 50%. Saturation is still 50% or 100%.
L=50% S=100% H=45 degrees: ORANGE
L=50% S=50% H=45: ORANGE-GRAY
L=50% S=100% H=135 degrees: CHARTREUSE
L=50% S=50% H=135: CHARTREUSE-GRAY
L=50% S=100% H=225 degrees: CYAN
L=50% S=50% H=225: CYAN-GRAY
L=50% S=100% H=315 degrees: MAGENTA
L=50% S=100% H=315: MAGENTA-GRAY

I will probably improve the English names of the 45 colors so far by looking up the Web standard HTML names of those.
I do not know if I can or want to have 45 basic (monomorphemic underived) color terms in Adpihi and Reptigan.
Maybe I’ll go with 11 basic color terms for those “primary” colors, and for the next 34 make them be either basic or “quasi-basic”.
I’ll define “quasi-basic”, in this context, to mean either monomorphemic but derived, or underived but bimorphemic.
….
The “tertiary” colors will also consist of three subsets.
• Both Lightness and Saturation are odd multiples of 25%. Hue is a multiple of 90 degrees. So this subset contains 16 colors.
• Lightness is an odd multiple of 25%, and Hue is an odd multiple of 45 degrees. Saturation is a multiple of 50%. This subset doesn’t contain any colors with S=0%, because LIGHT GRAY and DARK GREY were already covered in the first subset of “secondary” colors. So this subset contains 16 colors.
• Saturation is an odd multiple of 25%, and Hue is an odd multiple of 45 degrees. Lightness is 50%. So this subset contains 8 colors.

I would like to have names for these colors that didn’t imply they were all mixes of the primary and secondary colors; for instance, not hyphenated compounds of the names of those earlier colors. They might have to be quasi-basic or “meta-quasibasic”.
“Meta-quasibasic” means derived and bimorphemic, or underived and trimorphemic.

There are an additional 16 colors to fill up an Adpihi schoolkid’s crayon box of 101 colors.
These are the colors where both Lightness and Saturation are odd multiples of 25%, and Hue is an odd multiple of 45 degrees.
I never had any ambition to make any of these colors ‘basic’ or anything like “basic”.

…. …. …. ….
…. …. …. ….

This whole scheme is subject to change.

There’s another way to decide how basic or non-basic those same 101 colors would be.
Give each color one nonbasic point if H is not a multiple of 90 degrees.
Give each color one nonbasic point if L is not a multiple of 50%.
Give each color one nonbasic point if S is 50%; and two nonbasic points if S is 25% or 75%.

That gets us 7 perfectly basic colors; black, white, neutral gray, red, yellow, green, and blue.

There are also sixteen colors with only one non-basic point.
• Keeping L at 50% and S at 100%, there are four colors wherein H is an odd multiple of 45 degrees. Orange, chartreuse, cyan, and magenta.
• Keeping S at 100% and H at multiples of 90 degrees, there are eight colors where L is 25% or 75%. Dark red, light red, dark yellow, light yellow, dark green, light green, dark blue, and light blue.
• Keeping L at 50% and H at multiples of 90, there are four colors wherein S=50%; red-gray, yellow-gray, green-gray, and blue-gray.

I don’t think 23 basic color terms is wildly excessive. Natlangs tend to have not more than twelve, so this is less than twice that.

But so far I haven’t handled any colors with saturation at 25% or 75%.

Four sets of colors have only two non-basic points.

• Eight of them have L=50% and H a multiple of 90 degrees and S an odd multiple of 25%.
Reddish gray, grayish red, yellowish gray, grayish yellow, greenish gray, grayish green, bluish gray, and grayish blue.

• Ten of them have L an odd multiple of 25% and H an odd multiple of 45 degrees but S either 0% or 100%.
The two with S=0% are light gray and dark gray, depending on whether L is 75% or 25%.
The eight with S=100% are light orange, dark orange, light chartreuse (gotta be a better name!), dark chartreuse, light cyan, dark cyan, light magenta, and dark magenta.

• Eight of them have S=50% and L an odd multiple of 25% and H a multiple of 90 degrees.
My English names for them are { light | dark } { red- | yellow- | green- | blue- } -gray.

• Four of them have S=50% and L=50% and H an odd multiple of 45 degrees.
Orange-gray, chartreuse-gray (need better name!), cyan-gray, magenta-gray.

That adds up to 30 colors with two nonbasic points.
I’d like to have their colorterms be as nontechnical and natural-seeming as possible. The easiest or maybe most natural way would be to derive them (as monomorphemic words) from things that exist in nature on Adpihi but not on Earth. But that might leave readers or players scratching their heads. It might be better to somehow come up with a regular way to derive them bimorphemically from the first 23 colorterms.
53 basic colorterms is a major departure from natlangs, so I might have to limit my ambition to making this latest 30 be quasibasic or metabasic or almost-basic or next-to-basic.

…..

There are another 32 colors that have three nonbasic points. I might have to give up any ambition to make their color terms as basic as I can make them.
The final 16 colors have four nonbasic points; they’re the ones I left out in my first classification.

If a hex code is three bytes #rrggbb and we want to look only at colors with Saturation=0% then we want to look at those where rr=gg=bb.
We can get a five-color gray scale by limiting the bytes’ values to #00, #ff, #80, #40, #c0.
#000000 black L=0% S undefined H undefined #000000 black L=0% S undefined H undefined
#ffffff white L=100% S undefined H undefined #ffffff white L=100% S undefined H undefined
#808080 gray L=50% S=0% H undefined #808080 gray L=50% S=0% H undefined
#c0c0c0 silver L=75% S=0% H undefined #c0c0c0 silver L=75% S=0% H undefined
#404040 medium dark gray L=25% S=0% H undefined #404040 medium dark gray L=25% S=0% H undefined

The “pure hues” are the colors where L=50% and S=100%. That happens if, and only if, at least one of the bytes rr or gg or bb is ff, and at least one is 00.
There are six such colors codable using just 00 and ff.
#ff0000 red L=50% S=100% Hue=0 degrees #ff0000 red L=50% S=100% Hue=0 degrees
#ffff00 yellow L=50% S=100% Hue=60 degrees #ffff00 yellow L=50% S=100% Hue=60 degrees
#00ff00 lime L=50% S=100% Hue=120 degrees #00ff00 lime L=50% S=100% Hue=120 degrees
#00ffff aqua L=50% S=100% Hue=180 degrees #00ffff aqua L=50% S=100% Hue=180 degrees
#0000ff blue L=50% S=100% Hue=240 degrees #0000ff blue L=50% S=100% Hue=240 degrees
#ff00ff fuchsia L=50% S=100% Hue=300 degrees #ff00ff fuchsia L=50% S=100% Hue=300 degrees

There are another six colors codable with one ff byte and one 00 byte and one 80 byte. They’ll have lightness 50% and saturation 100%; but their hue angles will be odd multiples of 30 degrees.
#ff8000 Orange H=30 #ff8000 Orange H=30
#80ff00 Chartreuse H=90 #80ff00 Chartreuse H=90
#00ff80 Spring Green H=150 #00ff80 Spring Green H=150
#0080ff Dodger Blue H=210 #0080ff Dodger Blue H=210
#8000ff Electric Indigo H=270 #8000ff Electric Indigo H=270
#ff0080 Rose or Magenta Pink H=330 #ff0080 Rose or Magenta Pink H=330

A hexcode will represent a color with Lightness=75% and Saturation=100% if and only if the highest-value byte in the triplet is ff and the lowest is 80.
We can get six colors with L=75% and S=100% and Hues multiples of 60 degrees by using only the values 80 and ff; one value used once and one value used twice.
#ff8080
#ffff80
#80ff80

Group A.
Group A contains eight colors.

First the two poles of the color solid:
#ffffff lightness=100%, saturation undefined, hue undefined.
#000000 lightness=0% , saturation undefined, hue undefined.

Then six hues on the equator of the color solid:
#ff0000 L=50%, S=100%, H=0
#ffff00 L=50%, S=100%, H=60
#00ff00 L=50%, S=100%, H=120

#0000ff L=50%, S=100%, H=240
#ff00ff L=50%, S=100%, H=300

2+6 = 8 = 2^3

____________________________

Group B contains nineteen colors.
Groups A and B together are 27 colors

First is the absolute center of the color solid:
#808080 L=50%, S=0%, H undefined

Then six additional hues on the equator of the color solid (intermediate between those of group A; totaling twelve pure hues on the color solid’s equator):
#ff8000 L=50%, S=100%, H=30
#80ff00 L=50%, S=100%, H=90
#00ff80 L=50%, S=100%, H=150

#8000ff L=50%, S=100%, H=270
#ff0080 L=50%, S=100%, H=330

Then six saturated pastels on the solid’s surface along the latitude circle L=75%:
Halfway between white and the six pure hues of group A:
#ff8080 L=75%, S=100%, H=0
#ffff80 L=75%, S=100%, H=60
#80ff80 L=75%, S=100%, H=120

#8080ff L=75%, S=100%, H=240
#ff80ff L=75%, S=100%, H=300

Then their counterparts in the darker hemisphere, along the latitude circle L=25%:
Halfway between black and the six pure hues of group A:
#800000 L=25%, S=100%, H=0
#808000 L=25%, S=100%, H=60
#008000 L=25%, S=100%, H=120

#000080 L=25%, S=100%, H=240
#800080 L=25%, S=100%, H=300

1+6+6+6 = 19
19+8 = 27 = 3^3

____________________________

Group C contains 56 colors.
Groups A and C together are 64 colors

First there are two more grays on the gray scale, which is the axis of the color solid:
#aaaaaa L=67%, S=0%, H undefined
#555555 L=33%, S=0%, H undefined

Then there are twelve new pure hues on the equator of the color solid:
#ff5500 L=50%, S=100%, H=20
#ffaa00 L=50%, S=100%, H=40
#aaff00 L=50%, S=100%, H=80

#ff00aa L=50%, S=100%, H=320
#ff0055 L=50%, S=100%, H=340

Then six new saturated pastels about two-thirds white and one-third a pure hue from group A;
these are all on the surface of the color solid (ie they are saturated); they’re on the latitude circle for L=83%.
#ffaaaa L=83%, S=100%, H=0
#ffffaa L=83%, S=100%, H=60
#aaffaa L=83%, S=100%, H=120
#aaffff L=83%, S=100%, H=180
#aaaaff L=83%, S=100%, H=240
#ffaaff L=83%, S=100%, H=300

Their dark-hemisphere counterparts are six new saturated colors that are about two-thirds black and about one-third some pure hue from the equator in group A. They’re saturated (ie on the color solid’s surface) on the latitude circle for L=17%.
#550000 L=17%, S=100%, H=0
#555500 L=17%, S=100%, H=60

#000055 L=17%, S=100%, H=240
#550055 L=17%, S=100%, H=300

Then there are twelve colors that are not saturated, on the plane L=67%. Each is a mix of about one-third the #aaaaaa gray in this group, and about two-thirds one of the pure hues on the equator in group A or group B.
#ff5555 L=67%, S=67%, H=0
#ffaa55 L=67%, S=67%, H=30
#ffff55 L=67%, S=67%, H=60
#aaff55 L=67%, S=67%, H=90

#ff55ff L=67%, S=67%, H=300
#ff55aa L=67%, S=67%, H=330

Then there are twelve colors that are not saturated, on the plane L=33%. Each is a mix of about one-third the #555555 gray in this group, and about two-thirds one of the pure hues on the equator in group A or group B.
#aa0000 L=33%, S=67%, H=0
#aa5500 L=33%, S=67%, H=30

#aa00aa L=33%, S=67%, H=300
#aa0055 L=33%, S=67%, H=330

Then there are six colors that are even less saturated, on the plane L=50%. Each is a mix of about two-thirds the #808080 gray in group B, and about one-third one of the pure hues on the equator in group A.
#aa5555 L=50%, S=33%, H=0
#aaaa55 L=50%, S=33%, H=60

2+12+6+6+12+12+6 = 56
56+8 = 64 = 4^3

Group D contains 98 colors.
Groups A and B and D together contain 125 colors.

First are two new grays on the axis of the color solid (ie the gray scale).
Each is about halfway between the #808080 gray at the center in group B, and one of the color solid’s poles (ie white or black).
#c0c0c0 L=75%, S=0%, H undefined
#404040 L=25%, S=0% , H undefined

Then there are twelve new pure hues on the color solid’s equator. Each is intermediate between one of the hues in group A and one of the hues in group B.
#ff4000 L=50%, S=100%, H=15
#ffc000 L=50%, S=100%, H=45

Then there are eighteen new saturated dark colors. Each is about one-quarter black and about three-quarters one of the pure hues in group A or group C. These are all on the color solid’s surface, on the latitude circle L=38%.

There are six new saturated pastels on the latitude circle for L=75%. Each is halfway between one of the pure hues on Group B’s equator, and the color solid’s white pole. Each is halfway between two of the pastels in group B.

#ff80c0 L=75%, S=100%, H=330

There are six new saturated dark colors on the latitude circle for L=25%. Each is halfway between one of the pure hues on Group B’s equator, and the color solid’s black pole. Each is intermediate between two of the dark colors in group B.

There are twelve unsaturated colors each halfway between the color solid’s center, #808080 gray, and one of the pure hues on the equator in group A or B.
#c04040 L=50%, S=50%, H=0
#c08040 L=50%, S=50%, H=30

There are also six unsaturated colors on the plane L=62%. Each is about two-thirds a #a0a0a0 gray I haven’t discussed so far and don’t plan to discuss. I can’t think of a way to say each of these is a mixture of two colors I’ve already discussed.

If I go on to explicate or elaborate on “group E”, which consists of all of the “web-safe” colors except those in Group A, I don’t know if I’ll be able to finish before March 8 2022.
Group E will contain 208 colors.
Each will have a hexcode of three bytes; each byte can have any of six values independently of the values the other bytes have; and those values are the set {#00, #33, #66, #99, #cc, #ff}.

Group A and Group E together will contain 8+208=216=6^3 colors.

There’ll be four new grays on the gray scale (the axis of the color solid).
Namely:
#cccccc L=80%, S=0%, H undefined
#999999 L=60%, S=0%, H undefined
#666666 L=40%, S=0%, H undefined
#333333 L=20%, S=0%, H undefined

There’ll be 24 new pure hues on the color-solid’s equator.
I’ll try to see whether I can type them all in tonight.
#ff3300 L=50%, S=100%, H=12
#ff6600 L=50%, S=100%, H=24
#ff9900 L=50%, S=100%, H=36
#ffcc00 L=50%, S=100%, H=48
#ccff00 L=50%, S=100%, H=72
#99ff00 L=50%, S=100%, H=84
#66ff09 L=50%, S=100%, H=96
#33ff09 L=50%, S=100%, H=108
#00ff33 L=50%, S=100%, H=132
#00ff66 L=50%, S=100%, H=144
#00ff99 L=50%, S=100%, H=156
#00ffcc L=50%, S=100%, H=168
#00ccff L=50%, S=100%, H=192
#0099ff L=50%, S=100%, H=204
#0066ff L=50%, S=100%, H=216
#0033ff L=50%, S=100%, H=228
#3300ff L=50%, S=100%, H=252
#6600ff L=50%, S=100%, H=264
#9900ff L=50%, S=100%, H=276
#cc00ff L=50%, S=100%, H=288
#ff00cc L=50%, S=100%, H=312
#ff0099 L=50%, S=100%, H=324
#ff0066 L=50%, S=100%, H=336
#ff0033 L=50%, S=100%, H=348

(In my opinion spacing these hues just 12 degrees apart is much too fine-grained to be very much use. I’m not sure 15-degree intervals or intervals are all that useful either, tbh. I think 20-degree universals are great, though; as are 30-degree intervals.)

The other new saturated colors on the surface of the color solid will consist of the following subgroups.
24 new pastels at latitude L=60%, whose hues will be spaced 15 degrees apart;
18 new pastels at latitude L=70%, whose hues will be spaced 20 degrees apart;
12 new pastels at latitude L=80%, whose hues will be spaced 30 degrees apart;
6 new pastels at latitude L=90%, whose hues will be spaced 60 degrees apart;
24 new dark colors at latitude L=40%, whose hues will be spaced 15 degrees apart;
18 new dark colors at latitude L=30%, whose hues will be spaced 20 degrees apart;
12 new dark colors at latitude L=20%, whose hues will be spaced 30 degrees apart;
and 6 new dark colors at latitude L=10%, whose hues will be spaced 60 degrees apart.

There will also be another 60 unsaturated colors (that won’t be on the gray scale).
I think the biggest subgroup will be 18 at L=50% with S=60% (?) with hues spaced 20 degrees apart.
I think I probably ought to rest instead of saying anything else about them before tomorrow!

I never planned to create colorterms outside of groups A and B and C and D.
I never planned to include all of group D.
I think groups A and B together might be reasonable. They include 12 pure hues, which is close to the natlangish limit as far as I know.
And I don’t think 27 basic colorterms is too outlandish a stretch for a fictional conlang in a future setting. IIANM it’s just less than twice the RL natlangish maximum.

As for colorterms inclusive of non-basic colorterms, I think any school kid probably is quite capable of using a 64-term set, like one that might cover groups A and C.

A 125-term set, like one covering groups A and B and D, might also be within the average adult user’s grasp; it’s not too many more colorterms than there are keys on a typical 101-key keyboard. But it would probably be systematized so that, maybe, there’d be say about 16 basic terms, and systematic rules for deriving the rest from those.

Obviously I’m just free-associating here. I should rest and think, in one order or the other.

I’ve been thinking about how I could get close to my possibly-naive goal to have
5 values of Lightness (viz {0%, 25%, 50%, 75%, 100%}) and
5 values of Saturation (viz {0%, 25%, 50%, 75%, 100%}) and
8 Hues ({0 degrees, 45, 90, 135, 180, 225, 270, 315 degrees}).

If I allow each byte of a hexcode to vary thru 9 values {#00, #20, #40, #60, #80, #9F, #BF, #DF, #FF}
I come up with 9^3 = 729 colorcodes.
If the highest byte is #ff and the lowest byte is #00 the color is 100% saturated, S=100%, I think.
Otherwise if the highest byte is #df and the lowest byte is #20 the color is 75% saturated I think.
Otherwise if the highest byte is #bf and the lowest byte is #40 the color is 50% saturated I think.
Otherwise if the highest byte is #9f and the lowest byte is #60 the color is 25% saturated I think.

Perhaps I could investigate some subset of these 729 colors and see what they look like.

#ff0000 L=50% S=100% H=0
#ff2000 L=50% S=100% H=8
#ff4000 L=50% S=100% H=15
#ff6000 L=50% S=100% H=22
#ff8000 L=50% S=100% H=30
#ff9f00 L=50% S=100% H=38
#ffbf00 L=50% S=100% H=45
#ffdf00 L=50% S=100% H=52
#ffff00 L=50% S=100% H=60

#df2020 L=50% S=75% H=0
#df4020 L=50% S=75% H=10
#df6020 L=50% S=75% H=20
#df8020 L=50% S=75% H=30
#df9f20 L=50% S=75% H=40
#dfbf20 L=50% S=75% H=50
#dfdf20 L=50% S=75% H=60

#9f6060 L=50% S=25% H=0
#9f8069 L=50% S=25% H=30
#9f9f60 L=50% S=25% H=60

#808080 L=50% S=0% H undefined

As we see, for a given lightness (L=50% in the above case), the less saturated the colors are the fewer hues we can fit in and still notice the differences.

=============================

Now I will hold the saturation steady at S=100% and steadily raise the lightness from L=50% to L=100%, seeing how many hues I can fit in at each lightness.

First off there are the 48 hues at L=50% S=100%, represented by these 9;
#ff0000 L=50% S=100% H=0
#ff2000 L=50% S=100% H=8
#ff4000 L=50% S=100% H=15
#ff6000 L=50% S=100% H=22
#ff8000 L=50% S=100% H=30
#ff9f00 L=50% S=100% H=38
#ffbf00 L=50% S=100% H=45
#ffdf00 L=50% S=100% H=52
#ffff00 L=50% S=100% H=60

There are 42 slightly-pastel saturated colors at L=56% S=100%, represented by these 8;
#ff2020 L=56% S=100% H=0
#ff2020 L=56% S=100% H=9
#ff2020 L=56% S=100% H=17
#ff2020 L=56% S=100% H=26
#ff2020 L=56% S=100% H=34
#ff2020 L=56% S=100% H=43
#ff2020 L=56% S=100% H=51
#ff2020 L=56% S=100% H=60

There are 36 somewhat more pastel saturated colors at L=63% S=100%, represented by these 7;
#ff4040 L=63% S=100% H=0
#ff6040 L=63% S=100% H=10
#ff8040 L=63% S=100% H=20
#ff9f40 L=63% S=100% H=30
#ffbf40 L=63% S=100% H=40
#ffdf40 L=63% S=100% H=50
#ffff40 L=63% S=100% H=60

There are 30 yet more pastel saturated colors at L=69% S=100%, represented by these 6;
#ff6060 L=69% S=100% H=0
#ff8060 L=69% S=100% H=12
#ff9f60 L=69% S=100% H=24
#ffbf60 L=69% S=100% H=36
#ffdf60 L=69% S=100% H=48
#ffff60 L=69% S=100% H=60

At L=75% S=100% there are 24 saturated colors exactly halfway between white and a pure hue. They are represented by these 5;
#ff8080 L=75% S=100% H=0
#ff9f80 L=75% S=100% H=15
#ffbf80 L=75% S=100% H=30
#ffdf80 L=75% S=100% H=45
#ffff80 L=75% S=100% H=60

At L=81% S=100% are 18 saturated colors that are closer to white than to pure hues. These 4 represent them.
#ff9f9f L=81% S=100% H=0
#ffbf9f L=81% S=100% H=20
#ffdf9f L=81% S=100% H=40
#ffff9f L=81% S=100% H=60

At L=87% S=100% are 12 saturated colors that are about seven-eighths white. These 3 are representative.
#ffbfbf L=87% S=100% H=0
#ffdfbf L=87% S=100% H=30
#ffffbf L=87% S=100% H=60

At L=94% S=100% are 6 saturated pastels that are mostly white (or nearly white). These 2 are representative.
#ffdfdf L=94% S=100% H=0
#ffffdf L=94% S=100% H=60

At L=100% there is only one color; white. It’s saturation is undefined but we can group it with S=100% as justifiably as with S=0%.
#ffffff L=100% S undefined H undefined

As can be seen, for a fixed saturation — S=100% in this case — the further Lightness gets away from L=50%, and the closer it gets to L=100%, the fewer hues we can fit into the colorspace.

A similar thing would happen if L were to decrease from L=50% to L=0%. The further L gets from 50% and the closer it gets to 0%, the fewer hues can be fit in.

=======================

So what does it look like if I keep the hue constant but let the lightness and saturation vary?

New approach at my original goal.

First, the whole grayscale from white to black. This is the axis of the color solid.
#ffffff L=100%, S undefined, H undefined #ffffff L=100%, S undefined, H undefined
#bfbfbf L=75% S=0% H undefined
#808080 L=50% S=0% H undefined
#404040 L=25% S=0% H undefined
#000000 L=0%, S undefined, H undefined #000000 L=0%, S undefined, H undefined

Next, the entire equator at L=50% S=100%.
#ff0000 L=50% S=100% H=0
#ffbf00 L=50% S=100% H=45
#80ff00 L=50% S=100% H=90
#00ff40 L=50% S=100% H=135
#00ffff L=50% S=100% H=180
#0040ff L=50% S=100% H=225
#8000ff L=50% S=100% H=270
#ff00bf L=50% S=100% H=315

Then the two latitude lines at L=25% and L=75%. The ones at L=25% are half-black.
#800000 L=25% S=100% H=0
#806000 L=25% S=100% H=45
#408000 L=25% S=100% H=90
#008020 L=25% S=100% H=135
#008080 L=25% S=100% H=180
#002080 L=25% S=100% H=225
#400080 L=25% S=100% H=270
#800060 L=25% S=100% H=315

The ones at L=75% are pastels.
#ff8080 L=75% S=100% H=0
#ffdf80 L=75% S=100% H=45
#bfff80 L=75% S=100% H=90
#80ff9f L=75% S=100% H=135
#80ffff L=75% S=100% H=180
#809fff L=75% S=100% H=225
#bf8fef L=75% S=100% H=270
#ff80df L=75% S=100% H=315

Then the rest of the cross-sectional plane through L=50%.
There are circles at S=50% and S=75% and S=25%.
The ones at S=50% are half a neutral gray and half a pure hue.
#bf4040 L=50% S=50% H=0
#bf9f40 L=50% S=50% H=45
#80bf40 L=50% S=50% H=90
#40bf60 L=50% S=50% H=135
#40bfbf L=50% S=50% H=180
#4060bf L=50% S=50% H=225
#8040bf L=50% S=50% H=270
#80409f L=50% S=50% H=315

The ones at S=75% are three-quarters a pure hue and one-quarter neutral gray.
#df2020 L=50% S=75% H=0
#dfaf20 L=50% S=75% H=45
#80df20 L=50% S=75% H=90
#20df50 L=50% S=75%H=135
#20dfdf L=50% S=75% H=180
#2050df L=50% S=75% H=225
#8020df L=50% S=75% H=270
#df20af L=50% S=75% H=315

The ones at S=25% are one-quarter a pure hue and three-quarters neutral gray.
#9f6060 L=50% S=25% H=0
#9f8f60 L=50% S=25% H=45
#809f60 L=50% S=25% H=90
#609f70 L=50% S=25% H=135
#609f9f L=50% S=25% H=180
#60709f L=50% S=25% H=225
#80609f L=50% S=25% H=270
#9f608f L=50% S=25% H=315

Next are the rest of the colors at a depth of S=50%.
There’s a circle at L=25% and a circle at L=75%.
The circle at L=25% S=50% may be easier to calculate.
#602020 L=25% S=50% H=0
#605020 L=25% S=50% H=45
#406020 L=25% S=50% H=90
#206030 L=25% S=50% H=135
#206060 L=25% S=50% H=180
#203060 L=25% S=50% H=225
#402060 L=25% S=50% H=270
#602050 L=25% S=50% H=315

There is another circle at S=50% L=75%.
#df9f9f L=75% S=50% H=0
#dfcf9f L=75% S=50% H=45
#bfdf9f L=75% S=50% H=90
#9fdfaf L=75% S=50% H=135
#9fdfdf L=75% S=50% H=180
#9fafdf L=75% S=50% H=225
#bf9fdf L=75% S=50% H=270
#df9fcf L=75% S=50% H=315

So far that is 5 + 8*8 = 69 colors.
There are an additional 32 = 4*8 colors where L is either 25% or 75% and S also is either 25% or 75%.

For L=25% S=25% we get the following eight colors.
#503030 L=25% S=25% H=0
#504830 L=25% S=25% H=45
#405030 L=25% S=25% H=90
#305038 L=25% S=25% H=135
#305050 L=25% S=25% H=180
#303850 L=25% S=25% H=225
#403050 L=25% S=25% H=270
#503048 L=25% S=25% H=315

For L=25% S=75% we get the following eight colors.
#701010 L=25% S=75% H=0
#705810 L=25% S=75% H=45
#407010 L=25% S=75% H=90
#107028 L=25% S=75% H=135
#107070 L=25% S=75% H=180
#102870 L=25% S=75% H=225
#401070 L=25% S=75% H=270
#701058 L=25% S=75% H=315

For L=75% S=25% we get the following eight colors.
#cfafaf L=75% S=25% H=0
#cfc7af L=75% S=25%H=45
#bfcfaf L=75% S=25% H=90
#afcfb7 L=75% S=25% H=135
#afcfcf L=75% S=25% H=180
#afb7cf L=75% S=25% H=225
#bfafcf L=75% S=25% H=270
#cfafc7 L=75% S=25% H=315

Finally for L=75% S=75% we get these eight colors.
#ef8f8f L=75% S=75% H=0
#efd78f L=75% S=75% H=45
#bfef8f L=75% S=75% H=90
#8fefa7 L=75% S=75% H=135
#8fefef L=75% S=75% H=180
#8fa7ef L=75% S=75% H=225
#bf8fef L=75% S=75% H=270
#ef8fd7 L=75% S=75% H=315

That’s a total of 69 + 4*8 = 69 + 32 = 101 colors.

I could omit the 16 colors in which each of L and S is an odd multiple of 25% and H is an odd multiple of 45 degrees.
That would still leave 85 colors.

I don’t think 101 colors is too many for a trained adult to recognize and name provided most of the terms can be systematically derived from a smaller set (perhaps 10 or 11) of monomorphemic terms.

There is some question how recognizable the differences will be when L is close to 100% or 0% or when S is close to 0%.
The further L is from 50%, the harder — maybe — it is to tell the differences between closely similar values of S.
And the further L is from 50% perhaps the harder it is to distinguish between similar values of H.
And also, the closer S is to 0%, the harder it may be to tell the differences between similar values of H.
I don’t know whether those difficulties should just be skipped and those differences not be reflected in the vocabulary.
