Summarize the following:
Looking at a color wheel can help you to sift through the many different hair colors and select one that will look good on you.  For example, if you have cool, pale skin, then opt for warm colors, such as golden browns and copper reds. If you have tan skin, then opt for cooler hair colors, such as ash browns and blondes. If you have warm undertones with yellow, pick a hair color that leans towards like chestnut, dark golden brown, auburn and mahogany. Then highlight using a red base, such as cinnamon or copper. If you choose a blonde base or blonde highlights, you may end up overemphasizing your yellow undertone. If you have cool tones with a pink or blue undertone, look for an intense brown, red, or blonde base. Then, pick highlights that have a honey-wheat or ash look. This will help contrast your cool undertones. Choose burgundy, cherry, or garnet hair color for dark skin with cool undertones. You can use these as a base color or highlight color. The cool red tones in this hair color give your skin a smooth even look.

Summary:
Select a shade that is the opposite of your skin tone on a color wheel. Choose a deep rich base for your hair color. Choose an intense color base for your hair.
