I'm doing a wedding cake in January that has black (and maybe red) piping on white fondant. I've never done one with that color combo and i'm nervous about the black bleeding on the white. I use MMF and either royal icing or buttercream to pipe with.

Does it actually bleed? And if it does, what is a good way to prevent it? Is there a better frosting to use to pipe that wont bleed? TIA!!!

*Just wanted to add, i'm SURE this has been asked before, but i'm not sure how to search it. If someone wants to point me in the right direction to another thread, i'd appreciate that too!

I get the fairly large tubs of it in the Wilton aisle, it's clear and doesn't need much color to get rich black, way less than RI or BC would require.
