As I write, a window prism casts a cheery rainbow-stripe that drifts with the hours across my ceiling. Color perception, and our enjoyment of it, is part of our evolutionary legacy.

We have Sir Isaac Newton to thank for our understanding of the color spectrum. In the 17th century, he realized that when pure white light passes through a prism, it separates into seven visible ...

Why Purple Defies The Spectrum? Colors like red, green, or blue exist on the visible light spectrum — each corresponding to a specific wavelength of light. When sunlight passes through a prism ...

An intriguing photo projection system uses only black images and a prism to project full-color imagery. A Dartmouth College and Disney Research Zürich study could result in future systems that ...

The colors themselves are already in the white light, and all the prism does is to separate them out. As he put it, "Light consists of Rays differently refrangible" [meaning refractable].

ISAAK NEWTON, WIKIMEDIA COMMONS A round 1665, when Isaac Newton first passed white light through a prism and watched it fan out into a rainbow, he identified seven constituent colors—red, orange, ...

As if we needed any more proof, rainbow hair is here to stay. Unique colorful strands always catch my eye, whether it's denim dye, a subtle opal hue, or now, dramatic prism roots.This trippy trend ...

The electromagnetic spectrum, from highest to lowest frequency waves. (Image credit: Shutterstock) When we direct solar rays through a prism, we see all the colors of the rainbow come out the ...

MIT scientists create color-shifting films inspired by 19th-century holography ... of light, while a diffraction grating will produce the entire spectrum, much like a prism.

At least, when it comes to one color people think is on the spectrum. Popular Mechanics reports that purple is a “pigment of your imagination”: The human eye doesn’t actually see purple.
