How do I get nice gray fondant? I have tried gray icing in the past and it cracks or separates to a purplish tint? Want to make a shark cake and need nice gray fondant color. Help?!?

Adding black to white fondant will give you a nice gray. Do a little bit at a time to get the shade of gray you want.

what i did for the sponge bob cake i made i just used white foundant and added very little black to it until it was the color of grey i was looking for. hope that helps a little.

I read this question last week, and I seem to recall the advice also given was to use Americolor gels rather than Wilton colors...several people stated that adding Wilton black to white fondant resulted in that purplish hue you experienced.

If you are already using Americolor...well...nevermind
