What does a level system in hair color refer to?

The level system in hair color is a standardized scale that categorizes colors based on their lightness or darkness. This scale typically ranges from 1 to 10, where 1 represents the darkest shades, such as black, and 10 represents the lightest, such as pale blonde. Understanding this scale is crucial for colorists, as it helps them identify and communicate the desired shade to clients and ensure consistent coloring results.

This system allows professionals to determine how much lift (lightening) a color will achieve and assists in formulating the right color mixes. By using the level system, hair colorists can create a wide range of shades, from deep, rich colors to bright, pastel tones, while maintaining a clear understanding of the tonal value associated with each level.
