These are some basic types of color schemes to help you pick complementary colors for your wedding.
Monochromatic: One base color is used throughout, but there are several different hues and tones present. For instance, you may choose blue as your color. The bridesmaid’s dresses can vary in color from navy to periwinkle to powder blue and have a stunning visual effect through this color scheme.
Adjacent: Two or three colors are chosen that are adjacent to the color wheel. An example of this is to have yellow, yellow-green and green tones throughout the wedding.
Triadic: Three colors are used, that are equidistant from each other on the color wheel (in the shape of a triangle). For instance, a bride may choose yellow, blue and red for her colors.
Complementary: This scheme is very popular for weddings. Two colors are chosen that are opposite on the color wheel. Two examples are using red and green or using violet and yellow. (source: usabride)
Complementary Colors Definition: Two colors on opposite sides of the color wheel, which when placed next to each other make both appear brighter. The complementary color of a primary color (red, blue, and yellow) is the color you get by mixing the other two (red + blue = purple; blue + yellow = green; red + yellow = orange). So the complementary color for red is green, for blue it’s orange, and for yellow it’s purple. (source: about.com)
