Squid and octopus are able to interpret color and use it to great effect in camouflage, despite only being able to see in black and white.

The cuttlefish, known as the "chameleon of the sea," can rapidly alter both the color and pattern of its skin. Researchers at Harvard and MBL now understand the biology and physics behind this process.

In a new paper, Harvard researchers show that changes in coat color in mice are the result not of a single mutation, but of many mutations, all in a single gene. “For each of the mutations associated with color change, we also find a signal that’s consistent with positive selection,” said Harvard Professor Hopi Hoekstra.

Researchers have developed a system — inspired by nature — that allows soft robots to either camouflage themselves against a background, or to make bold color displays. Such a “dynamic coloration” system could one day have a host of uses, ranging from helping doctors plan complex surgeries to acting as a visual marker to help search crews following a disaster.
