The purpose of using a color wheel in hair coloring is to identify complementary colors. Complementary colors are those that are opposite each other on the color wheel. By understanding this relationship, cosmetologists can create balanced and harmonious hair color results. For instance, if a client has unwanted brassy or warm tones in their hair, a cosmetologist can look to the color wheel to find the appropriate cool tones that will neutralize those unwanted colors. This foundational principle helps professionals make informed decisions when mixing colors or selecting shades, ultimately leading to better outcomes for their clients.

The other options pertain to different aspects of cosmetology that do not relate to color theory or the use of a color wheel. Selecting shampoo involves understanding hair and scalp types rather than color relationships, while determining hair texture is more about the physical characteristics of the hair itself. Checking client allergies involves health and safety protocols, which also do not connect to the functionality of a color wheel.
