In this article I will try to explain the math behind converting RGB values to HSL and back.

RGB is a way to describe a color in a cube, where Red, Green and Blue are on the different axis.

Laser Holograms as Thin as a Hair Could Be the Future of High-Res

Laser Holograms as Thin as a Hair Could Be the Future of High-Res | color grading | Scoop.it

 

Holograms are cool enough on their own, but amazing things happen when you make them incredibly small.

 

A team of Army-funded scientists from Purdue did just that with the development of tiny holograms—smaller than the width of a human hair!—made by shining lasers through a metasurface.

 

This could change display technology forever.
