Aww, that's pretty cool.
Here's something I don't get about myself. There is a convention in faucetry that red indicates hot water and blue indicates cold water. For the vast, vast majority of people, this is completely intuitive. Not for me. I always think red indicates cold water and blue indicates hot water. (Just now in the hotel I drank some hot water because of that misinterpretation. Which I have made a thousand times.)
