If you aren't familiar with this site, I highly recommend it for crafting and painting and probably other higher pursuits!
You can choose colors from photographs, upload color themes into graphics programs, search for color combo ideas. It's fun and useful!
My bedroom colors are evolving...so much for my IKEA pillow inspiration. Here's the next idea. It was inspired by my IKEA duvet cover PLUS an upholstered ottoman I saw at Target. Given the intensity of our green choice, I decided that we should go for a nature-inspired palette and keep everything else neutral!
