an additive color model in which red, green, and blue light are the three primary colors. RGB is a convenient color model for computer graphics because the human visual system works in a way that is similar - though not quite identical - to an RGB color space. For the 24 bit color depth, each of RGB parameters (primary colors) can use a value ranging from 0 (no light, black) to 255 (full intensity of the colored light). For example, a bright red color might have an R value of 246, G value of 20, and B value of 50. Combining two additive primary colors in equal intensities produces the additive secondary colors cyan, magenta, and yellow. Combining all three primary lights (colors) in equal intensities produces a shade of gray; when the value of all three parameters is 255, the result is pure white; when all three parameters have values of 0, the result is pure black. Varying the full range of intensity of each light (color) eventually reveals the full gamut of those three lights (colors). color model color space computing & web
A color model in which colors are built by mixing the three additive primary colors red, green, and blue. In this model, you construct grays by including equal amounts of each primary: (0,0,0) is black and (1,1,1) is white. The RGB color model is closely associated with color CRT monitors because they use this model to produce their colors.
A model to represent colors as combinations of red, green, and blue.
(n) A color model based on the three additive primaries: (R)ed, (G)reen, and (B)lue. This color model is used extensively because of its close correlation to the hardware implementation of color on a computer monitor.
A method of specifying colors by blending red, green, and blue lights.
See Additive Color Model.
The RGB color model is an additive model in which red, green, and blue (often used in additive light models) are combined in various ways to reproduce other colors. The name of the model and the abbreviation â€˜RGBâ€™ come from the three primary colors, red, green, and blue. These three colors should not be confused with the primary pigments of red, blue, and yellow, known in the art world as â€˜primary colorsâ€™.
