A hair color's technical name is a letter-number combination that denotes its level and tone. For example, a warm dark blonde would be defined as 7W. Before taking your pick of hair colors, though, you need to ID your skin's undertones. Most people fall into one of three categories: warm, cool, and neutral.

The letters indicate the underlying tones—for example, Amalfi (in the uppermost left handcorner) is a “Neutral Gold Violet” blonde. C stands for copper, A is ash, R is red, and M is mahogany. Warm tones neutralize cool tones and vice versa.
Level 6 is another term for light brown hair. It is quite common in box dyes. Level 6 hair can also refer to the brighter shades of medium red hair. Most medium auburn shades are Level 5 or Level 6.
