What is the purpose of a color wheel in hair coloring?

The purpose of a color wheel in hair coloring is to help professionals determine complementary colors and corrections. Complementary colors are those that are opposite each other on the color wheel, meaning they can neutralize each other when mixed. For instance, if a client has unwanted brassy tones in their hair, a stylist can refer to the color wheel to find the opposite color that will counteract those tones, allowing for effective color correction. This tool is crucial in achieving the desired results and ensuring that hair color looks balanced and vibrant. Additionally, understanding the relationships between colors on the wheel helps stylists create harmonious color combinations and make informed decisions during the coloring process.
