What factor does a stylist consider to determine the lightness or darkness of hair color?

The level of color is a crucial factor that a stylist uses to determine the lightness or darkness of hair color. In hair coloring terminology, "level" refers to the specific degree of lightness or darkness on a scale that ranges typically from 1 to 10, with 1 being the darkest black and 10 being the lightest blonde. This scale allows stylists to communicate effectively about hair colors and select the appropriate shade or tint that will meet the client's needs or desired look.

Therefore, when a stylist assesses the level of color, they can match it with the right products and techniques to achieve the desired outcome, ensuring satisfactory results for their clients. Recognizing and understanding the levels of color is fundamental in color theory within the hairdressing profession, making it an essential component of hair coloring decisions.
