Revolutionizing electronic paper displays, E Ink has released a three-pigment display called 'Spectra.' Initially only available in black and white, the new displays can take on a third color. Either red, blue or green can be used to complement the initially monochromatic displays.

E Ink demonstrated the displays with red in order to show how useful they are in a retail environment. The third color can create eye-catching displays without the need to constantly print out new price or sales signs.

The displays are also able to be used in colder environments. E Ink's new screen can withstand cold temperatures up to -25 Celsius. This feature was built in to allow the signs to be used in colder retail environments such as freezers.
