Photography School: Color Wheel

There are three primary colors - red, yellow and blue. Combinations of these three colors produce three secondary colors: purple (red and blue), green (blue and yellow) and orange (yellow and red). Further mixing of these colors can produce a whole range of tertiary colors from which to compose your photographs. Usually, these colors are arranged in what is known as a color wheel which can be seen below.
