I used Americolor Super Black to make a light-medium gray and it has a purple hue to it. I used Michele Foster's fondant recipe. This didn't happen with Satin Ice before. Kneading in a bit of orange helped, but not significantly. This particular bottle was opened about 3 months ago. What's going on?

I know when I tried to make gray with the wilton black it did that too. I started using the Make-n-mold oil based black and it was perfect! It's used to color candy melts. I know that doesn't help you now but thought I'd share.....

Do you have the link on here to the color wheel? I can't find it right this second but it'll help you know what color to add to neutralize the purple. I know when mine turns green I have to add red. I know Americolor black isn't supposed to discolor but mine still does. Black fondant is my arch nemesis!
