Yeah, I personally wouldn't call it Skittles because it isn't made of Skittles. I wouldn't call it M&Ms either because you really don't need to whore out the brand of candy you used to make the design with.
I would spend some time trying to find something catchy. My Little Candy: Zechora (or Pinky Pie, or whatever). I came up with that in an instant. Chances are you should be able to come up with something eye catching, non brand-whoring, and exhibits what you do.
