Here’s where it gets nuts. A frog’s skin isn’t green. Nope.
Frog skin has two layers. The top layer is yellow. The bottom layer reflects blue light. When light hits the frog, the yellow filters out everything except blue. The blue bounces back, hits your eye, and… wait for it… your brain says “green.”
The frog is a living magic trick. It doesn’t own a single green pigment. It just fools you. Evolution is a comedian.
