While I'm enjoying a few of Trader Joe's potstickers before a meeting I have tonight I thought I'd post a link to a fabulous new website I found. Colorjive is one of those websites that I invented in my head and then thought someone must have already thought of it so I googled it and it turned out someone had (this also happened with Bookswim).
In essence, upload a photo of a room and digi-paint it! Get an idea of how the room will look in any color you choose. I did our living room and kitchen. You can see it's a bit smudgy, but not half bad at all when you're just trying to get an idea of how the room will look. As you'll see in the living room picture, I was even able to try out the red curtains.
