Food coloring for sugar cookies?!

Food coloring for sugar cookies?

I am making some cut-out sugar cookies and want to top them with colored sugar. I have a set of the common food dyes that you buy in the grocery store. What food colors do you combine to make brown? I read an article that advised using cocoa instead because when people see brown, they expect to taste chocolate. Any advice? Thanks!

You should use chocolate. I know that I am a chocolate lover so if I see a baked good, I would be thinking chocolate. To not taste chocolate (or cinnamon or brown sugar for that matter) in a baked good would be disappointing. Also people say you should use powdered food coloring, they say it is better b/c it doesn't leave an after-taste.
