Thank you @bleke I actually am reading this discussion and appreciate how passionate everyone are with it.
This is actually expected with RYB, in real life when you blend it with a medium, oil or watercolor, it results in dull purple and cyan. That’s where CYMK shines, it should produce vibrant purple and have cyan as a primary color. It actually produces reasonable vibrant red hue too. I should post the color wheels I did with watercolor and gouache to compare, but I feel it deserves a new thread under a more proper category? I don’t know. I’m one of those who likes to experiment with such things.
@Emanuele Which version are you using. I’m using the latest version and it could be mixed to green without picking anything. It’s actually the first software that actually does it well. I’m not counting artrage’s real color blending because it turns into a neon green color when I do that and that’s annoying because that’s not how real life color mixing works so hence it shouldn’t be called real color blending in the first place.
