DON'T try mixing Wilton's white and black. You'll get a purple. Their black seems to have a lot of red in it.

Thankfully the purple turned out ok for the cake I was doing it for, but it could've been a disaster!

Grey is not as simple as it seems

Wiltons Black - gives you a purplish grey
Americolor - gives you a greenish grey

Try add little bits of YELLOW - you will fidn you get a great GREY pretty quickly

I have had pretty good success mixing the Satin Ice Black (I keep a small tub on hand) with white fondant but I don't use Wilton white so not sure this was helpful.

Pam,
Add yellow to which? Wilton Black or Americolor, or both?

You need to add whichever color is missing. To neutralize a purple color (red plus blue) add yellow. To neutralize a greenish color (yellow plus blue) add red.

ALL "blacks" will have a non-black tone to them once they are lightened.

This helps to explain it
