RGB codes use light mixing rules. This is fine, can take some getting used to if you are used to pigment.
RYB would be a primary color code scheme. It wouldn't cover the same range of colors. I'm thinking about how one would code a conversion function between the two from "first principals" ... I think RYBB would allow the same range of colors if "B" is black.

@futurebird I think blue having the same first letter as black is why they refer to black as "key" in CMYK

@futurebird
I think it'd miss some of the brighter colours. Red and Blue aren't really primary colours for paint, which is why printing uses CMYK(edited: wait of course you know that. Nearly did a full-on mansplain there!)
So would this be light mixing with RYB and some combination rule that isn't just addition and subtraction?

@futurebird CMYK Cyan (blue) Magenta (red) Yellow Black.

@futurebird CMYK Cyan (blue) Magenta (red) Yellow Black.
That's for printing? And so it's also confusing. The color system most people learn is RYB for some reason. I don't know why.

@futurebird CMYK Cyan (blue) Magenta (red) Yellow Black.
This is coming from working with students who learn about "primary colors" in art class, but then in tech I have this other system and it confuses them a little. (they adapt)

I'm trying to help students who learn RYB understand light mixing with less difficulty.

Makes sense. I think introducing CYMK to the mix would just make it more confusing?
Also I want to puzzle this out. But I don't understand why so many people are taught that Red Yellow and Blue are the primary colors?
That's the real issue. I will bother the art teachers tomorrow.

@futurebird what you are after is called CMYK

@futurebird if it’s less confusing you can call C “blue” and M “red”;
i can explain why kindergarteners are taught red yellow and blue but it it’s sort of my big infodump thing. hard to type out here. pigment paints are a bit different from both light mixing and printer’s ink mixing

@futurebird in the big girl painting classes to get a full range of colours you actually need at least two of each, a purple leaning red (alizarin crimson) orange leaning (cadmium red) , purplish blue (ultramarine blue) greenish (pthalo blue), cadmium yello, burnt umber, burnt sienna, then we have dioxazine purple which has an intensity you cannot get by mixing any of the blues or reds; and greens that you cannot get with the blues and yellows
and each of these mix in strange and confusing ways: alizarine is strong, use only a little. yellows are weak.. etc
to understand why you need spectral vision and microscopic vision to see the mechanics of the pigment mix

@bri_seven @futurebird yessss I want a class where I can mix pigments and get a brown mess, then look in a microscope and see colors again.

careful, @futurebird . The galaxy of color spaces contains many strange new worlds and you may fall through the wormhole into the gamma quadrant and voyage for many years without finding a way home ...
