I'm having a problem filling a layer with my desired color. (Note: This is sort of hard to describe, so I hope I make it clear.) I created a a layer in my image with black lines. I want to fill the lines of this layer with a color that I picked from another layer in the same image. But when I use the magic wand to select the black lines and select "fill," it won't fill with the color I picked from the other layer. I try both secondary and primary, and neither of them allow me to fill the selections with my desired color.
I hope I've described the situation clearly. It's frustrating because it should be simple, and I know it's something I'm doing wrong, but for the life of me I can't figure out what it is. Thanks in advance for any insights!
