Grey or gray (see spelling differences) is a colour between white and black. It is a colour seen commonly in nature and fashion. In pigment, or subtractive color (CMYK), it is created by adding black. In light, or additive colour (RGB), it is created by adding equal amounts of R, G, and B, 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 colour 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 colour, with colder light adding a yellow-orange hue and warmer light adding a blue hue.

Two colours are called complementary colours if grey is produced when two colors are combined. Grey is its own complement. Consequently, grey remains grey when its colour spectrum is inverted, and therefore has no opposite, or alternately is its own opposite. On a more abstract level, it could be argued that colours which produce grey when mixed, such as black and white, are the opposite of grey while separated. However, this could not be considered the literal opposite of grey.

[edit] Colour coordinates

RGB 
All the grey values in greyscale are solutions of the inequality:
0 \le ( R = G = B ) \le 255
CMYK 
All the grey values in greyscale are solutions of the inequality:
0 \le K \le 255 when C = M = Y = 0 \,.
In theory it is also possible to achieve a greyscale with perfect inks when:
C = M = Y \, and K = 0 \,
HSL 
All the grey values in greyscale fit one of the following three equalities:
S = 0 or L = 0 (black) or L = 1 (white).
HSV 
All the grey values in greyscale are solutions of the inequality:
0 \le V \le 1 when H = S = 0 \, .

[edit] Web colours

There are several shades of grey available for use with HTML and CSS. Oddly, all are spelled with an a except lightgrey: this can cause unexpected errors (this discrepancy is inherited from the X11 colour list). Note that the three "slategray" colours are not themselves on the greyscale, but are slightly saturated towards cyan (green + blue).
