I am currently developing a puzzle game which requires the player to blend colors in order to solve the puzzles. I am using the RYB model because I think it's the most logical when it comes to blending colors : green is blue + yellow. I'm cheating a bit to avoid very dark colors, my colors are bright as if I was working with light.

I am introducing secondary and tertiary colors to make the puzzles more challenging. However, I am having a bit of trouble handling 1 case : what happens when someone mixes orange with blue? Or purple + yellow? Or green + red? Do they result in the same color? What is the hue of this color based on the hue of the primary colors that were used? I have no paint to try this out, and I'm not sure how to simulate those mix on Photoshop

  • Shouldn't your algorithm already calculate this result for you? Commented Aug 21, 2018 at 14:43
  • No algorithm involved here, since the player can only use primary colors and cannot paint over a ternary color, the number of possibilities is so little that I hardcoded the resulting colors so I can have the shades I want

  • I would strongly recommend... DO NOT USE the RYB model. It is an archaic model.

    Might be, though IMHO, I don't think many people would think that green+red=yellow when playing

The precise colours achieved would depend on the particular shade of colours mixed.

However, generally speaking, in subtractive colour systems (such as CMYK or RYB): orange + blue, yellow + purple, and red + green, all make various shades of brown or greyish brown. In fact, if you mix any red, yellow, or blue primary colour with a non-primary colour (with the exception perhaps of red and orange), then you will probably get some shade of brown - or as I like to refer to it "mud".

If you want to experiment with real paint, then get some red, yellow, and blue paint, and try mixing them up yourself.

The example below might be a bit more accurate than the one above. Here I used MyPaint which simulates paint and blending of paint colours.

enter image description here


The resulting colors from the mixing of the complementary colors, or the opposites in the chromatic circle, and the corresponding ones towards black and white; in Spanish are called colores quebrados or colores rotos (broken colors, sorry I didn't find any equivalence in English). I'll use the name of broken colors for this answer, maybe someone helps with the real english name.

    Hello Danielillo, is there a script you used to create these colour maps?

    No, it's Illustrator blending.
