The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: cyan, magenta, yellow, and key (black).
Pantone [ 1 ] ISCC–NBS descriptor. Dark grayish olive. B: Normalized to [0–255] (byte) Pantone 448 C is a colour in the Pantone colour system. Described as a "drab dark brown " and informally dubbed the "ugliest colour in the world", it was selected in 2012 as the colour for plain tobacco and cigarette packaging in Australia, after market ...
Special-purpose color spaces. The rg chromaticity space is used in computer vision applications, and shows the color of light (red, yellow, green, etc.), but not its intensity (dark, bright). LMS color space (long, medium, short), a perceptual color space based on the response functions of the cones in the retina of the eye.
Red, green and blue lights, representing the three basic additive primary colors of the RGB color system, red, green, and blue. Pure yellow light is composed of equal amount of red and green light. The color box at right shows the most intense yellow representable in 8-bit RGB color model; yellow is a secondary color in an additive RGB space.
25-pair color code chart used in certain kinds of wiring. A color code is a system for encoding and representing non-color information with colors to facilitate communication. This information tends to be categorical (representing unordered/qualitative categories) though may also be sequential (representing an ordered/quantitative variable).
As such, color spaces are an essential tool for color reproduction in print, photography, computer monitors, and television. The most well-known color models are RGB, CMYK, YUV, HSL, and HSV. Because the perception of color is an important aspect of human life, different colors have been associated with emotions, activity, and nationality.
In printing, grey is usually obtained with the CMYK color model, using cyan, magenta, yellow, and black. Grey is produced either by using black and white, or by combining equal amounts of cyan, magenta, and yellow. Most greys have a cool or warm cast to them, as the human eye can detect even a minute amount of color saturation. Yellow, orange ...
In the CMYK color model, the primary colors magenta, cyan, and yellow together make black, and the complementary pairs are magenta–green, yellow–blue, and cyan–red. Color printing, like painting, also uses subtractive colors, but the complementary colors are different from those used in painting. As a result, the same logic applies as to ...
