Summarize this article:

The color wheel is a map of colors, showcasing the ways new colors can be created. There are three sets of colors present: primary, secondary, and tertiary. Primary colors are: red, blue, and yellow. These are colors that come straight from a tube; they cannot be made from mixing other colors. However, secondary colors (purple, green, and orange) can be made from the primary colors. Tertiary colors are in between primary and secondary on the color wheel (think teal or peach).  Red + Yellow = Orange Yellow + Blue = Green Red + Blue = Purple Adding a small amount of white to any color will make it lighter, turning it into a tint. Most from-the-bottle colors are very vibrant and bold, and can be made more pastel-like by adding white. It is harder to add white to a color, so try adding a bit of your color to white paint first. You will have to use less paint to make a tint in this fashion. If a color is too bright for your liking, mix the color’s opposite into it to dull the vibrancy. Doing this is changing your hue (true color) into a tone; you’re toning the color down. A color’s opposite is the one directly across from it on the color wheel. For example, the opposite of red is green, yellow is violet, and blue is orange.

Summary:
Familiarize yourself with the color wheel. Create different tints. Create different tones.
