I CAN HAS COLORCHECKER?

Due to popular demand, and after all there can never be too many photos of cats on the Internet, here is one I took today of my kitten Hamish.  I was actually setting up to photograph some cosmetic products when he confused the backdrop for something I wanted him to sharpen his claws on.  Hamish's colour is close to 18% grey (although he's a British Blue), but his fur isn't as reliable as the ColorChecker (sic) Passport I use for product photography to ensure that the colours in the images I produce are accurate and consistent.
