There are only three main colors that make up all the other colors in the world. Without them there would be no colors. These three colors are red, yellow, and blue.
We call these colors the Primary Colors.
All other colors can be created by mixing the primary colors in various combinations. For example:
Yellow + Red = Orange
Red + Blue = Violet
Blue + Yellow = Green
It's easy to mix Dyes to make new colors. You can use the primary colors (red, blue, and yellow)
Mixing the Primary Colors
The Color Wheel:
The Color Wheel shows how the three primary colors (and the other colors) relate to each other. The primary colors are red, yellow, and blue; they are the only colors that cannot be made by mixing two other colors. The three secondary colors are green, orange, and violet; they are each a mixture of two primary colors. Their hue is halfway between the two primary colors that were used to mix them.
