Have you the about Flor tiles? Flor has an online site and you could mix and match pink and gray tiles to get a neat pattern. We don't have then in our house but have some experience with them and they are pretty easy to clean (you just pull up the one square affected and spot treat/hand wash) so they are good for kids rooms. Be sure to look for discount codes too if you do order online. I have seen some on retailmenot before.
