Grey
Wikipedia, the free encyclopedia - Cite This Source- This article is about the color. For other uses, see Grey (disambiguation) and Gray (disambiguation).
In color theory
Most grey pigments have a cool or warm cast to them, as the human eye can detect even a minute amount of saturation. Yellow, orange and red create a "warm grey". Green, blue, or purple, create a "cool grey". When there is no cast at all, it is referred to as "neutral grey" or simply "grey".
| WARM GREY | COOL GREY |
| Mixed with 6% yellow. | Mixed with 6% blue. |
Two colors are called complementary colors if grey is produced when they are combined. Grey is its own complement. Consequently, grey remains grey when its color spectrum is inverted, and so has no opposite, or alternately is its own opposite.
Artists sometimes use the two different spellings to distinguish between strict combinations of black and white versus combinations that have elements of hue.
Web colors
There are several shades of grey available for use with HTML and CSS in word form, while there are 254 true greys available through Hex triplet. All are spelled with an a: using the e spelling can cause unexpected errors with outdated browsers (this discrepancy was inherited from the X11 color list), and to this day, Internet Explorer's Trident browser engine does not recognize "grey" and will not render it. Another anomaly is that "gray" is in fact much darker than the X11 color marked "darkgray;" this is because of a conflict with the original HTML gray and the X11's "gray," which is closer to HTML's "silver." The three "slategray" colors are not themselves on the greyscale, but are slightly saturated towards cyan (green + blue). Note that since there are an even (256, including black and white) number of unsaturated shades of grey, there are actually two grey tones straddling the midpoint in the 8-bit grayscale. The color name "gray" has been assigned the lighter of the two shades (128 also known as #808080), due to rounding up. In browsers that support it, "grey" has the same color as "gray."

Color coordinates
RGB- Grey values result when r = g = b, for the color (r, g, b)CMYK
- Grey values are produced by c = m = y = 0, for the color (c, m, y, k). Lightness is adjusted by varying k. In theory, any mixture where c = m = y is neutral, but in practice such mixtures are often a muddy brown (see CMYK#Why black ink is used).HSL and HSV :
- Greys result whenever s is 0 or undefined, as is the case when v is 0 or l is 0 or 1
In human culture
Environmentalism- Greys has been used pejoritavely by environmentalists to describe technophiles as being those who like granite, concrete and other city materials, as opposed to the term "greens" to describe those in favor of environmentalism.
- In a moral sense grey is either used
- pejoratively to describe situations that have no clear moral value, or
- positively to balance an all-black or all-white view (for example, shades of grey represent magnitudes of good and bad).
- In folklore, grey is often associated with goblin folk of several kinds. Scandinavian folklore often depicts their gnomes and nisser in grey clothing. This is partly because of their association with dusk, partly because these races, including elves (see below), often are outside moral standards (black or white).
