My natural hair color is a pretty plain brown, but right now, I have it dyed red. Again. Well, the dye was burgundy, but it wasn't dark for very long. I'm not sure if I really messed up the dye job, if the dye itself wasn't that great, or if it's the shampoo I'm using. :/ It's still pretty red, though.
My eyes are hazel. It's not quite brown, but not quite green, either... it kind of depends on the lighting.
