I'm sure this has been covered before but I did a search and couldn't find an answer that would help me 
I'm trying to make gray fondant. I tried adding some Black Satin Ice fondant that I have, to white fondant, and it made lavender. Tried using the wilton gel color, I'm getting purple/lavender again.
I recall encountering the same problem when making gray royal icing awhile back, the Wilton Black gel only turns purple for me! (See the 2nd pic under my photos, the one with the blue flowers, the purple parts were supposed to be gray. Any ideas on how to just get a solid gray?
Thx guys! Working on a cake for a local high school's musical they're putting on, my first paid gig, so excited!
The only thing that has worked for me was to use Americolor Super Black in white fondant. (I've made several elephants, one for a Seussical the Musical cake and a couple for baby showers, so I'm glad they were gray, not purple or green, as I have seen with Wilton black coloring.)
One thing that is important is to let the fondant sit for a while for the color to fully develop.
If you can't get the Americolor gel, all may not be hopeless. I think somebody mentioned that you can look on a color wheel to see what is opposite the color your fondant is (e.g., purple or green) and add that color (the one opposite) to make black. I think that, for purple, you would add yellow, but I'm not sure on that.
You could try adding a little bit of blue to it, that might tone down the purple. Also, do you have any white? That might help.
