Which one of the major food colorings Holds its color the best over a long period of time in gum paste flowers. I have found out that the wilton food coloring fades pretty fast.
I use Americolor. It is awesome!!
Well, I will try that when it comes to coloring my flowers. I do like how it colors fondant.
dont forget to use petal dusts - they make a world of difference to your final colour.
