Finding out what hair color suits you is based on the cool and warm tones of your skin. For example, cool is mostly Asian skin for they have the brown base. Warm is Causasin for their skin base is pink. For cool stay away being too light (blonde thin highlights are ok, all blonde is a big no-no). Warm skin tones should stay away from being too dark; jet black would make you look pasty and washed out.
Suggestions: Cool tones-reds, dark browns, light gold, or red brown. Warm tones- golden blonde, light brown, light red. These colors are great for either highlighting or an all over color. I hope this helps.
