I have some left over ivory colored fondx fondant. I need some royal blue and red. If I dye the ivory, will it come out okay?
I've never worked with Fondx, but I would think it would be ok. I make my own Marshmallow Fondant and constantly use leftover light colored pieces and dye them a darker color.
I would suggest trying a very small portion first.
I don't use Fondx, but otherwise I do the coloring thing all the time. I start out with any light color and end up with anther color. "Waste not, want not."
I don't see why it wouldn't work! but i have made some colours i didn't expect so i recommend taking a little piece and seeing what colour shows up when adding the red or blue... once you know how to get the colour you want, do the same with the bigger piece and then mix both pieces together.
