It is time to create with all the colors of the rainbow (or just one if that is your preference)! For the Colors of the Rainbow Contest make a project of any kind that either uses all the colors or focuses on just one: Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Besides having a Grand Prize winner with the best overall project who will win a Canon camera, we will also be giving away 3D printers to eight individuals with the best project for each color including rainbow.

Get your supplies together, it's time to make the rainbow. 

The Colors of the Rainbow Contest is closed.
