In photography, complementary colors are defined as a color and its opposite on the color wheel. For example, primary blue and yellow are considered complementary colors. If we want to make a feature stand out from its background, we can photograph it against its complementary color, for example yellow aspen leaves against a deep blue Colorado sky. Other complementary color pairs are primary green and magenta; and primary red and cyan. Every color on the color wheel has an opposite, or complementary color. The color wheel below illustrates the color relationships.

Note that colors that are close to each other on the color wheel are called "harmonious" colors, such as green foliage against a blue sky, or yellow flowers in a field of green.
Your assignment for the week of 2 - 8 March 2009 is "Complementary Colors." You should photograph a scene that uses complementary colors to emphasize an object against its background, or emphasize the color contrast between objects in a scene. Please upload your images to the "Complementary Colors" album in the Weekly Assignment category in the Gallery no later than midnight, Mountain Time (GMT -07:00) on Sunday, 8 March 2009.
I'll look forward to seeing your images! :)
