Red and blue are both primary colors. This means that they cannot be made by mixing other colors together. When two primary colors are mixed together, the new color is called a secondary color, and varying shades can be produced depending on the amount of each primary color in the mix. All secondary colors are placed on the color wheel between the colors that were mixed to create them.
