Yes, I realize this bunny bears no mask. I drew him on a whim with my mouse as I was showing a friend about masking layers in Photoshop and how it can help her with a project she’s working on. Starting out, I said, “I’m going to draw something really lame now.” But as we worked on the colors, his little crooked self kind of grew on me. Anyway, thought I would share.
Masks are excellent shortcuts for coloring lined art. Make a separate layer for each color and brush it in. (Don’t forget to label them appropriately and group as well if you have a lot of elements on the same file.) Then magic wand the line art area on the line art layer. Switch to the color layer, click the mask icon and viola! Your colored splotch is now trimmed up.
