Grey or gray (see spelling differences) describes any shade between black and white. Collectively, white, black, and the range of greys between them are known as achromatic colors or neutral colors. Greys are seen commonly in nature and fashion. Grey paints can be created by mixing complementary colors (that is colors directly opposite on the color wheel, e.g. yellow and violet). In the RGB color model used by computer displays, it is created by mixing equal amounts of red, green, and blue light. Images which consist wholly of neutral colors are called monochrome, black-and-white or greyscale. Achromatic means literally “without color”.

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
