The role of a color wheel in hair coloring is primarily to help determine complementary colors and the effects of mixing colors. A color wheel serves as a visual guide that shows the relationships between different colors, which is essential for hairstylists when selecting hair dye or formulating custom colors. By understanding where colors lie on the wheel, stylists can identify which colors work well together, such as complementary colors that can neutralize unwanted tones in hair. This knowledge allows for better decision-making when aiming for specific results in hair coloring processes, ensuring a harmonious balance and desired outcomes.

The other options relate to different aspects of hairstyling and product selection. While mixing colors is certainly a part of the color wheel's utility, the specific emphasis on complementary relationships is crucial for achieving the intended results in hair cosmetics. Selecting the best product brands and assessing hair damage levels are important considerations in the overall hairstyling process but are not directly associated with the primary function of the color wheel.
