so lately I've been diving into color theory and started art school, but my problem is applying them to my tattoo's, I use to do B&G first then lay color over it but I'm just beating up the skin more than it needs, so I wanted to try to start using more contrasting colors and different shades for my pieces, but lets say I'm doing a red flower when I lay green down then red it always muddys up and I've mixed in the tube and same results, what am I doing wrong? do I just put the green and the red next to it and not over lap it, also do I want to lay a really bright red and a dark green correct, any help would be greatly appreciated, thanks guys!!!
