Just had to correct people's incorrect usage of the term highlights.
Highlights are bleach treated sections of hair, lifting color/removing pigment, resulting in light brown, carmel or blonde.
Lowlights is any color, depositing color/pigment. Example, black, brown, red, pink, blue ect.
Anyway, Chloe, I think you should keep your naturally dark hair, but put in natural red lowlights, and streaks of blue. It would look awesome in any lighting.
