Here’s a uncanny fun fact: roughly zero in inlet is blue.
You competence say, “but a sky is blue, we idiot.” While that is something we’re taught given we were small, a law is that a sky usually appears blue. This is due to a Tyndall effect, or a approach light reflects off of sparse particles.
Even birds we competence consider are blue, like a blue and yellow macaw, usually seem blue since of nanochannels within their feathers that change a approach light reflects. So if you’ve got blue eyes, we guessed it, there’s no blue colouring in there. But since do they demeanour a approach they do?
