Researchers from Yale-NUS College and the University of Fribourg have discovered a color-generation mechanism in nature, which if harnessed, could potentially be used to create screen displays that project the same image when viewed from any angle, and even to reduce the signal loss in optical fibers.

Researchers from Yale-NUS College and the University of Fribourg in Switzerland have discovered a novel colour-generation mechanism in nature, which if harnessed, has the potential to create cosmetics and paints with purer and more vivid hues, screen displays that project the same true image when viewed from any angle, and even reduce the signal loss in optical fibres.
