I am having trouble making red and black icing color my red looks pink and my black looks gray can anyone help me please?

Americolor gels work great for coloring. You can buy them at almost any online cake supply. They are inexpensive too. They really beat the wilton colors.

For the black I would start with chocolate icing though. You wont need to add some much black.....and you wont have black teeth.

It helps to mix the colours well in advance, because they will darken over time. Mix them the night before if you are able to.

And a big welcome to CC, LissaAnne!!

Here is the list of acronyms...you'll find it helpful!

I did a mickey cake and found (as previously mentioned) AmeriColor worked best - I found that I still need to use more than I would normally use to get the right colour for Mickey.

I just did a Mickey Mouse cake (it's in my photos if you're interested in seeing the colors). I used the no taste red from Wilton. It does deepen with time. I also used Wilton's black. It took a TON of paste but I was able to get it very black. It looks a bit dark gray in my picture but that's because I didn't brush off the extra powdered sugar in time for the photo.

Thank you all so much these tips has really helped!
