Physicists and vision scientists are lining up behind a provocative claim: the rich color we call purple is not a property of light at all, but a story the brain tells itself. Light in the real world ...

Described as a kind of blue-green, the new color—named “olo”—can only be seen using lasers to manipulate certain ...

Team develops a flexible and stretchable device capable of omnidirectional color wavelength control. A team at Pohang University of Science and Technology (POSTECH), spearheaded by Professor Su Seok ...

a) Illustration of the omnidirectional wavelength-tunable color device featuring a mechanochromic chiral liquid crystal elastomer (CLCE) and an electrically deformable dielectric elastomer actuator ...

The color purple is, in a way, invented by our brains. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The world is awash with the color purple — ...

To overcome the lack of wavelength-selective extraction in existing on-chip metasurfaces, Chinese scientists developed a novel approach by leveraging a nonlocal on-chip design based on symmetry-broken ...

For example, the coatings on tinted eyeglasses reflect, or "block out," harmful blue light and ultraviolet rays. But until now, no optical coating had ever been developed that could simultaneously ...
