Who says ceilings should be white?

When I was in high school I somehow convinced my parents to let me paint my ceiling yellow.  (To compliment my then beachy blue-green walls.)  After a minor miss-hap where I spilled the yellow paint on my white carpeting, I got my yellow ceiling and still love it.   The sunny hue is an awesome contrast to the thick white crown molding I had previously begged my parents for.

Here now in my rental apartment, I'm wishing I could add a similar fun color to my boring white ceiling. Unfortunately, I think the hassle of painting it back when we move out is enough to prevent me from taking the time to do it.  Either way. I've been perusing pictures, imaging what I could be looking up to.

How awesome is this bright green and white trim?

Or, the awesome stripes that Jenna Lyons put on her sons roof?

I don't even like purple, but I love it on this kitchen ceiling!
