I have found that many people aren't sure what colors they want to have as their wedding colors. If you are wanting a more elegant feel to your wedding, you don't really want too many colors. It is suggested no more than one or two colors, combined with one neutral (whites, beige/tans, blacks). Below are some color charts that you may find helpful.
Some things to remember; Primary Colors are: Red, Yellow, Blue; Tertiary Colors are: Orange, Green, Purple. Complimentary Colors are those that are opposite on the color wheel: Red & Green, Yellow & Purple, Blue & Orange.
