>>5843892>GX basic colorsThey are really good colors but I wouldn't use them for mixing.
The reason you get shit color is because all "finished" colors are basically pigment + white base and when you mix them you get twice the white.
MrColor has CR line for color mixing and Gaia has its own CMYK set and they are basically clear colors where you mix them to what you want and then add white in the end.
tl;dr if you need violet, buy violet, not blue and red
