I am making a castle cake for my son's birthday and am fairly new to cake decorating. I was wondering how do I get grey frosting for the outside walls/stones?

Are you using buttercream or fondant? Either way you just add a little black to white. Some color charts say to also add a touch of blue. I've never added the blue. I just use the black myself.

thanks ladies! i don't have black so i was wondering if there was any other specific color combination (3 red to 5 blue to 2 yellow...), but it's probably best just to get some black to add to my white buttercream.

I always have issues with grey so when I need it I usually buy some pre-made black and mix it in with my white. I don't make grey that often. For some reason black food coloring just doesn't do it for me, but the already made black, (I usually just run out and get wilton tubes of frosting or the pack of fondant that has browns, flesh and black,) works great. A little goes a long way so you're not putting a ton of nasty tasting Wilton stuff in there.
