I'm making a cake with several gumpaste pieces (paintbrushes, cups etc..) I painted the color on them with food color paste mixed with vodka. If i place these on a white buttercream iced cake the night before delivery will the colors bleed on the buttercream? Some of the colors are very dark (black, purple, blue).
Anyone??? I wish i had a few extra peices to try it out ahead of time but i don't.
