Complementary colours are specific pairs of colours from the colour wheel as follows:
Red/Green Yellow/Purple Blue/Orange
For this contest, the subject of your photos can be anything you like but the two main colours must be one of the pairs listed above. Small amounts of other colours are permitted. If the two main colours in the photograph are not the pairs listed above, then during crowd rating, please mark the photograph as not on brief.
Every photo submitted will be available for the crowd to rate once the submissions period has ended. You can see all the images uploaded to a contest, but will need to rate them to see how they’re ranked once the rating period begins.
Some contests on Photocrowd also have a judge. After the submission period closes the judge chooses their favourite images and writes some image reviews. The crowd and judge results will be announced on the same day.
