I have brown hair (naturally) that I dye red (but I haven't dyed it for a while). I wear whatever red I want, honestly! I have two reds by Smashbox that I think are divine reds (one darker, one bright hot red). I'm very, very, very fair complexion though and a lot of people say red looks great on me because of that porcelain doll thing.
I am a true believer that anybody can wear reds though---regardless of what type of red, what type of skin color etc. I think it's more about confidence than anything. I'm not a confident woman, per se, but once I got used to wearing reds I developed a whole new confidence for it specifically.
