I looked online the other day and someone said that you can mix equal parts yellow, red and blue food coloring to make black. I tried it and it didn't work. Is it possible to make black food coloring or should I just buy black pre-made already.

If you can buy black icing where you live I would recomend buying that, If you cant then sugarflair sell a good black past, I have in the past bought black liquid food colouring from the supermarket and boiled off the excess water this makes a really good black.

Yeah, I have a few places I can buy the black. Thanks for the advice for boiling down the liquid.

Chefmasters black is wonderful, no fail

Just buy black food coloring. If you are going to tint fondant black, I suggest you get ready made black or start with chocolate fondant.

I have to say rylan, not to disrespect . Make sure first you want chocolate taste on your cake before doing the fondant with a chocolate base. My clients wouldnt go for that. So I have to do my fondant or buy it premade black.

Oh yes Edna, I understand . She has a point. Make sure your clients approve for it. That doesn't really apply to me because I only make my cakes as gifts and I get to choose the flavors.
