The new weeks theme is listed here. https://virily.com/challenges/the-last-two-weeks-of-the-color-crazy-challenge/
The last two weeks of the challenge is to use the rainbow! You can write about the rainbow, do a poll or quiz, or post a photo or art piece. You can also pick your favorite color of the rainbow and post about it. Perhaps you have some monochrome or monotone pieces that you would like to share? Monochrome is only one color. You can even use color splash, highlighting a certain object or color in a black and white photo?
Here are some ideas!
