Producing technicolor through brain-like electronic devices

Structural coloration promises to be the display technology of the future as there is no fading—it does not use dyes—and enables low-power displays without a strong external light source. However, the disadvantage of ...

Engineers manipulate color on the nanoscale, making it disappear

Most of the time, a material's color stems from its chemical properties. Different atoms and molecules absorb different wavelengths of light; the remaining wavelengths are the "intrinsic colors" that we perceive when they ...
