Ever wonder why you are more attracted to some paintings than others? Quite often it's color. For example, if there is green in a painting, red always looks good with it. It settles it down and it's easy on the eye. Any colors that are opposite in the color wheel are called compliments and compliments look good together. Red is opposite green in the color wheel. Yellow is opposite violet. Orange is opposite blue. Then there are the mixed colors of all these with their mixed opposites. In other words you can mix yellow with green to get a lighter green and its opposite or compliment is a lighter violet, since yellow is opposite to violet.
It all starts with yellow, red and blue plus white. Any painting can be done using only these four colors.
