Easy color changing with layer masks
I really hope someone can help me out with this, I'm struggling so hard to remember how to do this! It's been a hot minute since my last digital illustration class, and I remember that we used some sort of layer style or tool that allowed us to paint where we wanted color to apply to a layer using layer masks. Then, if you wanted to change the color, you click on the square next to it, bring up the color palette, and then choose the color. Sorry if this sounds confusing, I have a picture below, I found it in one of my old files. How the heck do you make this and what's it called?!
