You shouldn't feel held back by your hair, MadCadaver, as long as you're willing to give it lots of TLC and attention. Since you're asking for a color you think you should dye it, if you're going for duel tones, I'd say make the bottom layer a much darker brown, and maybe the top layer a fiesty pumpkin color. For just the bottom, I'd say dark brown, or maybe a burgandy. I constantly keep my hair a shade of burgandy called pommegranate, and it's great!!.
And hey, be proud of your hair, it's part of who you are! ^^ *plus it's sooo adorable*
