What colors of food coloring make grey,I'm making a Bugs Bunny Cake?

I didn't know it until trying to find an answer for you, but apparently McCormick now has Black Food Coloring like they have red, yellow, blue and green. I suggest you try and find a bottle of it in your area and then add a few drops at a time to your regular frosting (assuming your normal buttercream frosting is basically white like mine) or make a really white cooked 7 minute frosting. Beat in the few drops of black coloring until you get the shade of gray you want - don't forget it looks a little darker when dry than when whipping it.

It sounds like a cute cake. Will Bugs have an orange carrot also?

Tinted cream cheese orange and used 2 drops orange foodstuff co,Irving and 3 drops purple foodstuff coloring and cream cheese grew to become a easy crimson. How lots extra purple and orange foodstuff coloring to characteristic to make orange

What's wrong with the obvious

It's gonna be hard without white. Maybe blue will work alone

i did not know that there was now black food coloring--thnks,good to know

blue and red and a bit of green i think
