Clone with Git or checkout with SVN using the repository’s web address. Over the course of millions of years, the human eye has evolved to detect light in the range 380—780nm, a portion of the electromagnetic spectrum known as visible light, which we perceive as colour. Though, not all of the colors in the spectrum can be synthesized by this method. Physics Light Colour. A Gamma menu was added, allowing the native RGB companding function to be overridden.
