RGB

Red Green Blue.

Projected light (as opposed to reflected light like that of printed material) is a composite of the primary colors red, green, and blue. These 3 colors can be used to produce almost all other colors through mixing at various levels. This is how TVs, monitors and projectors work.

RGB is an additive color model, meaning that overlapping colors add to one another. So full red + blue + green is white, whereas in a subtractive color model, such as paints or ink, that combination would produce a muddy black-brown.

Red + Blue = Magenta (violet) Blue + Green = Cyan (light blue) Green + Red = Yellow Red + Blue + green = White

This mixing of colours is used in LED tv's to provide a very thin and very clear tv picture.
