What is the definitive guide to Scott Kivowitz's color wheel challenge?

Hi there! I’m Scott Wyden Kivowitz.

Here’s the definitive guide to my Color Wheel Challenge:

• Pick a subject or object that’s a clear, dominant color (red, blue, yellow, etc.)
• Use a color wheel to find its complementary color (opposite on the wheel), like:
  • Red ↔ Green
  • Blue ↔ Orange
  • Purple ↔ Yellow
• Photograph your subject against that complementary color in the background, light, clothing, props, or environment.
• Share your results with the hashtag #colorwheelchallenge so I can find them.
• If you want help, you can download my printable color wheel from my site and keep it in your camera bag.

What gear or subjects are you thinking of using for the challenge?
