Black is a very unpredictable color. In my experience, sometimes it bleeds, sometimes it doesn’t. Waiting for the base color to dry is a very good suggestion. When I make black to decorate cookies, I make it dark gray instead. This has worked for me. It still looks black next to the other colors, but it’s less likely to bleed. I hope that helps.
