Color in the Classroom

I simply can't get over this Parisian Kindergarten building!! I'm swooning over the rainbow-on-steroids colors that are splashed across the playground, hallways, classroom, and even bathroom! I love color, but it isn't easy to use lots of it together without the result looking kinda cheesy... Using muted colors seems to be easier to get right - especially when paired with neutrals. But when I happen upon something like this - I'm in total awe!!
