I've been looking online for ways to blend colors in photoshop and I can't find anything that suits my needs. I was told there is a way to blend colors such that when I paint with a color then choose a different color and go over the previous one, it will pick up that color and mix it like paint. I've been trying other programs like: Sai, Art Rage and Corel Painter and they all do it. Corel painter seems to be the best but I'm not as accustomed to it as I am Photoshop and I'd like to stick with it if I can. It just seems strange that Photoshop wouldn't do it since every other program does.
So, is there a way or do I have to blend manually?
