In the future, e-reader owners may open up their devices to see full-color pages, rendered using the same methods octopuses use to show and hide colors. Some of the latest color e-reader technology in labs today mimics octopuses, cuttlefish and squid, according to a new study.

For instance, the world's physically lightest and best-quality color e-reader display, which is under development at HP, uses the same techniques that octopuses do when camouflaging themselves or showing off during mating displays.
