[By Design] RYB mode in MIXING Brush is messed up

Recommended Posts

As you can see in the image, mixing red and yellow gives you an ochre color, mixing magenta and yellow gives you a gray color, mixing blue and yellow does give you the holy grail of green but still has a cyan halo, at the end of the blend (which is not how it works in real life). In RGB mode everything works quite good (except blue+yellow).

Mypaint is an open source program which has dominated the mixing of colours, you should take a look at their forums and code, it might help you ;)

Are you using a third party brush? I get that is not a basic round brush....Does it happen to you also with a basic default round brush  ?

I had understood his issue to be a different one, indeed. I'm now not quite sure (what's RYB here?) what is happening in abn5x's machine... Still, I can't explain the cyan band appearance in the very right...Maybe a wet border effect...Or a monitor range physical limit ( in that case, is noticed if exported as file, and we could compare that. Probably a screenshot will show the issue, the file saved not).... But I trust more the developers than my zero idea about this issue. ( I have not noticed anything wrong in mixing colors myself)
