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: c yan, m agenta, y ellow, and k ey (black).
Possible lightness values are 15% through 90% in steps of 5% for monochromatic shades of grey (i.e. C = 0%) and 20% through 90% in steps of 10% and additionally 85% and 93%. Chroma values are also mostly confined to steps of 10% or 5%, but with some exceptions, and the maximum value varies.
Chartreuse ( US: / ʃɑːrˈtruːz, - ˈtruːs / ⓘ, UK: /- ˈtrɜːz /, [1] French: [ʃaʁtʁøz] ⓘ ), also known as yellow-green or greenish yellow, is a color between yellow and green. [2] It was named because of its resemblance to the French liqueur green chartreuse, introduced in 1764. Similarly, chartreuse yellow is a yellow color ...
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.
Magenta is variously defined as a purplish-red, reddish-purple, or a mauvish–crimson color. On color wheels of the RGB and CMY color models, it is located midway between red and blue, opposite green. Complements of magenta are evoked by light having a spectrum dominated by energy with a wavelength of roughly 500–530 nm.
Vivid yellowish green. B: Normalized to [0–255] (byte) Chartreuse green was codified to refer to this brighter color when the X11 colors were formulated in 1987; by the early 1990s, they became known as the X11 web colors. The web color chartreuse is the color precisely halfway between green and yellow, so it is 50% green and 50% yellow.
Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.
In color science, a color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers, typically as three or four values or color components. When this model is associated with a precise description of how the components are to be interpreted (viewing conditions, etc.), taking account of visual ...
