In color mixing, what color is created by mixing red and blue?

Mixing red and blue results in the color purple. This occurs because red is a primary color and blue is another primary color. When these two are combined, they create a secondary color, which is purple. This principle of color mixing is fundamental in art and design, where primary colors combine to form various secondary colors.

The other options reflect different combinations of colors. Green is created by mixing blue and yellow, orange is a result of mixing red and yellow, and brown is typically created by combining various colors, often red, yellow, and blue, but not directly by mixing just red and blue. Understanding these basic color relationships helps in various fields, including cosmetology, where color theory plays an essential role in hair dye and makeup application.
