This is a challenge that might run beyond just one week and be the start of your own personal project. Pick a color that means something to you. Your challenge is to take a series of photographs over the week (or a month, or a year) where that color dominates. As your collection of images grows in size, you can then group them together in interesting compositions. The results of this challenge is not just the individual photos you create, but the compositions or collages of images that you might create.

As ever, these challenges are to encourage new photography, not to simply re-use your existing stock. As such the Week 7 challenge is one that you might want to keep longer than just one week.
