The Colors of the Rainbow Contest is a celebration of color for all the chromatically-minded individuals out there. This contest is all about color coordination.

In addition to the usual Grand Prize and Runner Up winners, we are giving out special Judges Prizes for the best use of each color of the visible spectrum. If its been a while since seventh grade science class with Mr. ROY G. BIV, those colors are Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Pick one of these colors and show us a project that pushes it to its limit for your chance to win a 3D PRINTER!

If you happen to be super-indecisive and can't pick just one color, we are also giving away another Judges Prize for the best overall use of all of the colors of the rainbow. Show us a project that is an explosion of rainbow-y goodness for a chance to win this prize.

The Colors of the Rainbow Contest is closed.
