![]() ![]() Saturation is a percentage value between 0% (no color, i.e., gray) and 100% (i.e., pure color, fully saturated). Hue is a number between 0 and 360 that represents an angle on a standard color wheel. Because it depends on reflected light, CMYK has a smaller color gamut than does RGB.Ī color model that represents subjective colors in terms of three numerical dimensions: Hue, Saturation, and Brightness. A color specified as a mixture of these colors is called a process color, as opposed to a spot color. Printing that uses some mixture of cyan, magenta, yellow, and black ink is called four-color process printing. This model is called subtractive, because each color is produced by a pigment that absorbs (subtracts) a color from the light that is reflected from it to the eye. These four colors are called process colors. Used in light generating devices such as TVs and monitors.Ī color model that represents all colors by mixing together the three primary colors: Cyan (C), magenta (M), and yellow (Y), plus black (K). Any combination of these three lights that stimulates all three human color receptors equally will produce gray. This model is called an additive model, because each color is produced by adding together red, green, and blue lights. Illustrator supports three color models RGB, CMYK, and HSB.Ī subset of all the colors, which may depend on the medium, the output device, and the manufacture.Ī color model that represents all colors by mixing together the three primary colors: Red, Green, and Blue light. Note that the human eye works by comparing the output of 3 types of receptors that have their peak output very approximately at three primary colors. One of the general methods used in digital graphics to represent colors in terms of numbers that may correspond to a small number of primary colors or a small number of dimensions. One of a small number of colors that can be mixed together to produce the same impression as any of a wide range (gamut) of colors. Since the spectral colors fall in a linear range, but perceptual colors that are produced by mixing primary colors form a color wheel, some perceptual colors do not correspond to any single spectral color. ![]() The unmodified term color refers to perceptual color as represented on the color wheel. The term spectral color contrasts with the term perceptual color, or simply color.Ī perception of color that can arise from sensory stimulation by a single spectral color or by a mixture of primary spectral colors. TermĪ wave length of electromagnetic radiation that falls within the visible spectrum. Understanding Illustrator's color facilities requires familiarity with the following color terminology.
