Which combination of colors represents an example of two primary colors?

The combination of red and yellow represents two primary colors. In the context of color theory, primary colors are those that cannot be created by mixing other colors together. Red, yellow, and blue are the traditional primary colors used in the RYB color model, commonly applied in art and design. By mixing red and yellow specifically, one can create the secondary color orange.

This understanding of primary colors is foundational in cosmetology, particularly when working with hair color, makeup, or nail art where color mixing is used to achieve desired results. The ability to recognize and utilize primary colors effectively can enhance the aesthetic appeal of beauty treatments.
