There are a few skin tones that look good with red hair. If you have fair skin, then you can rock just about any shade of red. If you have olive skin, then you'll want to avoid orange-toned reds and go for shades with more blue or purple undertones. And if you have dark skin, then you'll want to stay away from reds that are too light, as they can wash you out. The best thing to do is experiment with different shades of red until you find one that compliments your skin tone.
