"The Blues" card from Hoote + Annie, found via where the lovely things are.
I'm inspired by this print. Not sure why this popped in my head. But wouldn't this be cool painted on the wall in a nursery or play room. It wouldn't be as overwhelming as a rainbow-bright color scheme, nor as kitschy as a wall mural. Just simply blocks of similar color hues. I think the color names are imperative, too. You've got to admit the words are a little more child-friendly than PMS colors. :) But what wonderful way to inspire creativity in a child--blue, there are so many different shades of blue.
