The bacteria _Serratia marcescens_ produces the enzyme responsible for its
bright pink color only in its optimum temperature, otherwise the colonies
appear white. And Siamese cats have their distinctive coloring because the fur
that is at cooler temperatures is brown. The back, tip of tail, paws, and
faces are cooler than the rest of their bodies. When they get older, and their
body temperature goes down, the brown starts to spread.
I wondered if temperature is responsible for change in eye color. Body
temperatures do generally rise in times of great emotion and I have heard of
other people whose eyes change similarly.
