I've never tried food coloring. I think I would be afraid to. I don't think it comes in as many colors as RIT and might be hard to get a good match. I've tried nail polish on patent leather and it didn't work at all!Has anyone tried food coloring or Easter egg coloring to refresh worn spots or "dye" a bag? I was trying to think of alternate ideas in place of acrylic paint, which I never have luck with in color matching. I also tried mixing some nail polish today to get the right color for corner touch ups on a cheapie non-leather bag I bought on Mercari. It worked pretty well but I don't think I'll try that for my leather bags. Just some ideas to toss around!
That was me! RIT works great. In the case of a suede bag, it worked much better than Fiebings suede dye, which just disappeared after brushing. You can paint it on to address only the spots that need it. I wouldn't recommend dunking in very hot water as they recommend since it melts edge coating, and don't add any salt if the instructions say so.I think someone uses RIT liquid dye with success.
