I know you use just a small amount of black but is there something else to make the gray pop. thanks

I make black icing (chocolate icing with black food coloring) and then add some of that to the white.  It gives a better looking grey then the purply blue grey that you get when you add black directly into white icing.

I always just use a tiny amt. of black to b/c , fondant, modeling chocolate , when i make grey. It turns out a beautiful grey that i want.

thanks!
 

I use black and I add a touch of yellow in with it. It takes out the purple tint.
