I found this page a long time ago, and I found it pretty fascinating. It explains why rats don't often make distinctions between colors but can tell even without sniffing if they have scent-marked stuff (UV rays).
I have found info like this in other places, so it's not really just made up here, but take it as you will. Just thought it was neat to share. Might help with cage decorating or trips outside, etc.
