And the tertiary colors are yellow-orange, red-orange, red-purple, blue-purple, blue-green, and yellow-green. The secondary colors are green, orange, and purple. The primary colors are red, yellow, and blue. There are three different types of colors. We will start off the year learning how to start with Primary Colors (red, yellow and blue) and mix them to make all of the other colors to construct a color wheel. Without a basic knowledge of color mixing you would have a hard time with painting. In the art world the color wheel is a map that shows which colors mix to make others and color schemes (how colors work together).
