Today's challenge was to choose a favorite color. My favorite color is red but I thought I try a little color theory with today's photo. I formed a color wheel using my grandson's crayons. The arrangement of the colors around the wheel help define both complimentary and analogous colors. Complementary colors can be found by choosing any color around the wheel and then looking straight across the wheel. For red the complimentary color is green, think Christmas. Yellow's complimentary color is violet and blue's is orange. Analogous colors are those on either side of main color. In the case of red, it's red orange and red violet. A color wheel is a very useful tool for decorators, artists, photographers and even a guy when picking a tie or socks to match that shirt.
