Color wheels show us how colors are related. They remind artists how to mix and think about colors. Primary colors cannot be made from other colors. Artists create all the other colors of the rainbow by mixing together the primary colors. Secondary colors are made by mixing two primary colors. Each secondary color is made from the two primary colors closest to it on the color wheel.
At grade 4 we was surprised when we found out that when the spin rolled , the colorful rainbow of colours turned into a charcoal gray.
