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 produces orange, while combining blue and yellow results in green. These secondary colors are essential in art and design, as they expand the color palette. In the color wheel, secondary colors are positioned between the primary colors they derive from. This arrangement helps artists and designers understand color relationships and create harmonious compositions. By using secondary colors, one can achieve a wider range of shades and tones in their work.
