Pretty Vases

I was in Crate and Barrel yesterday, wishing I had an extra $800 lying around to buy this chair, when I saw these vases, which were way more in my price range. Obviously I didn't get any, since I already have a few vases and rarely have flowers in them as it is. But I imagined all four of the colors lined up on a window sill, each with a different colored, single long stemmed flower basking in the sun. 

Sigh. I think I have to go back and get at least one. But then the question is, which color?
