What's the secret? I feel like when I try to color fonant it takes me FOREVER to get a rich color! I know that Wilton sells mulitpacks with bright colors in them but they get expensive when you need a bunch of it to cover a cake.
The easiest way is to make it yourself and add the color with the liquid.
One way to color a lot of fondant is to make a color starter. Make a smaller portion of fondant with very strong color, then blend the pigment into the remainder. It works a little easier.
