The color orange is made from mixing red and yellow together. Orange is a secondary color, which means that it is made by mixing two primary colors together. The three primary colors are red, blue and yellow.
There are also three secondary colors: orange, purple and green. If one of the secondary colors is mixed with the primary color directly beside it on the color wheel, the result is called a tertiary color. The six tertiary colors are red-orange, yellow-orange, yellow-green, blue-green, blue-violet and red-violet. From the tertiary level, colors can continue to be mixed to create an endless variety of different hues.
