I had a tub of Duff's black fondant, and I needed to make gray. So, I thought that logically, I could mix a little of the black fondant with my white to make gray... Wrong!! It was brown. Very brown. I thought I would share with y'all so that you could avoid this mistake in the future... I reckon I'll save the brown... I might have a use for it at some point.
I would have thought the same thing. I ordered some Americolor white. I will have to experiment with the white and black to see how that comes out.
