The RGB color model is an additive color model [1] in which the red, green, and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. [2] The main purpose of the RGB color model is for the ...
The 3-3-2 bit RGB use 3 bits for each of the red and green color components, and 2 bits for the blue component, due to the human eyes having lesser sensitivity to blue. This results in an 8×8×4 = 256-color palette as follows: This palette is used by: The MSX2 series of personal computers; Palette 4 of the IBM PGC; Extended Graphics Array (XGA)
If the color in the top layer is less than fully opaque (alpha < 255), the color from underlying layers "shows through". In the RGB model, hues are represented by specifying one color as full intensity (255), a second color with a variable intensity, and the third color with no intensity (0).
RGB color spaces are a category of additive colorimetric color spaces [1] specifying part of its absolute color space definition using the RGB color model. [ 2 ] RGB color spaces are commonly found describing the mapping of the RGB color model to human perceivable color, but some RGB color spaces use imaginary (non-real-world) primaries and ...
The Atari ST series has a digital-to-analog converter of 3-bits, eight levels per RGB channel, featuring a 9-bit RGB palette (512 colors).Depending on the (proprietary) monitor type attached, it displays one of the 320×200, 16-colors and 640×200, 4-colors modes with the color monitor, or the high resolution 640×400 black and white mode with the monochrome monitor.
In computer graphics, a palette is the set of available colors from which an image can be made. In some systems, the palette is fixed by the hardware design, and in others it is dynamic, typically implemented via a color lookup table (CLUT), a correspondence table in which selected colors from a certain color space's color reproduction range are assigned an index, by which they can be referenced.
Red (A), Green (B), Blue (C) 16 bit look up table file sample. (Lines 14 to 65524 not shown) In the film and graphics industries, 3D lookup tables (3D LUTs) are used for color grading and for mapping one color space to another.
sRGB has been the standard version of RGB for the web since 1996. As an RGB system, it describes the amounts of red, green, and blue light which are added together in order to create a particular color. Every color infobox on Wikipedia must have one such parameter to, at the very least, show on the screen an idea of what the color looks like.
