If you’re not too sure how cephalopods change color, don’t worry: It’s a chromatophoreign concept!
Cephalopod skin makes light work out of camouflage and communication with specialized cells. Chromatophores are pigment-filled sacs that expand and contract in a dynamic tapestry—usually in shades of red, brown and orange.
Iridiophores break up the light into brilliant blues and glorious greens like the surface of a soap bubble, and leucophores act like tiny mirrors to shine back white light, rounding out the cephy artist’s palette. It goes to show that wonderful works of art can be skin deep.
