Secondary colors are created by mixing two primary colors. The primary colors are red, blue, and yellow. When you combine red and blue, you get purple. Mixing red and yellow results in orange, while combining blue and yellow produces green. These secondary colors are essential in art and design, as they expand the color palette. Artists often use secondary colors to create depth and contrast in their work. Understanding how to mix colors can enhance creativity and improve visual communication in various fields, including painting, graphic design, and interior decorating.
