For seven weeks, we're asking for your best Photo Instructables based on that week's color. Each Monday we'll announce a new color of the week. At the end of the contest we'll name a winner in each color category. You could win an awesome Nikon Coolpix digital camera!

Week 7: Ultraviolet themed Photo Instructables!

Each week we're adding to the rainbow, so as of Week 7, red, orange, yellow, green, blue, purple and ultraviolet Photo Instructables are accepted.

Create a Photo Instructable with the predominant theme and you'll be entered to win! All photos must be of a finished project you have made. No stock photography will be accepted.

How It Works

Write an Instructable

Create a new Instructable that fits the guidelines outlined in the contest description above. To be eligible, Instructables must be published between May 16, 2011 and Jul 3, 2011 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Colors of the Rainbow Contest. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.


When the winners are decided they will be notified and announced here on the contest page.
