Grey or gray (see spelling differences) is a color between white and black. It is a color seen commonly in nature and fashion. In pigment,it is created by mixing complementary colors (that is colors directly opposite on the color wheel, e.g. yellow and violet). In light, or additive color, it is created by adding equal amounts of red light, green light, and blue light,(RGB) with R,G,B greater than 0% and less than 100% (greater than 0 and less than 255, in the 8-bit notation commonly used in computing). Depending on the color temperature of the light (measured in kelvins of a black body radiator), the human eye can interpret the same object as either grey or some other color, with colder light adding a yellow-orange hue and warmer light adding a blue hue.
