Orange is vibrant. It\'s a combination of red and yellow so it shares some common attributes with those colors. It denotes energy, warmth, and the sun. But orange has a bit less intensity or aggression than red, calmed by the cheerfulness of yellow. As a warm color orange is a stimulant.  Orange can be found in nature in the changing leaves of fall, the setting sun, and the color of citrus fruit. Orange brings up images of autumn leaves, pumpkins, and (in combination with Black) Halloween. It represents the changing seasons so in that sense it is a color on the edge, the color of change between the heat of summer and the cool of winter.

While orange and black are traditional Halloween colors, orange really pops with a medium blue. Red, yellow and orange can be a fiery hot combination or, in tamer shades, a fresh, fruity experience. Make it tropical with green. Mix orange and pink to recreate a vibrating, 60s psychedelic look. Try a dash of orange with deep purple or a dash of purple with a bit of orange, tempered by lots of mellow yellow or white for an eye-catching look that\'s not overpowering.
