I used to often pick the wrong hair colour shade for my hair then my hairdresser told me to pick tones and shades that flatter your skin tone. Choose warm shade of hair color (reds and warm browns) if you look best in warm-colored clothing such as reds, pinks and oranges. Choose a cool shade (beige, pale blonde highlights and neutral colors) if you look best in blues and greens. It really works there is nothing worse than changing your hair colour then finding out it looks to light or to dark. Many a times I have cried over my hair colour results
