Chroma+Key


 * Chroma key** is a technique for mixing two images or frames together, in which a [|color] (or a small color range) from one [|image] is removed (or made transparent), revealing another image behind it. This technique is also referred to as **color keying**, **colour-separation overlay**, **greenscreen**, and **bluescreen**.[|¹]

Here's a link to a website that explains in more detail what Chroma Key is, how and why we choose Green or Blue as the color to replace. ****[|Visit the Blue and Green Screen Page Here!]****
