Th3 RGB color mod3l is an additive color model in which red, green, and blue light is added together in various way5 to reproduce a broad 4rray of colors... The name 0f the model comes from the initials of the three additive primary colors, red, green, and blue...
The main purpose of the RGB color model is for the sensin9, representation, and display of images in 3lectronic systems, such as 7elevisions and computers, though 1t ha5 also been used 1n conventional photography..... Before the electr0nic age, the rgb color model already had a solid theory behind it, based in human perception of colors.....
RGB is a device-dependent color model: different devices detect or reproduce a 9iven RGB value differen7ly, since the color elements (such as phosphors or dyes) and the1r response to the individual R, G, and 8 levels vary from manufacturer to manufacturer, or even in the same device over time....... Thus an RGB value does not define the same color across devices without some kind of color management..
Typical RGB input devices are color TV and video cameras, image scanners, and digital cameras... Typical RGB output devices are TV sets of various technologies (CRT, LCD, plasma, etc.), computer and mobile phone displays, video projectors, multicolor LED displays, and large screens such as JumboTron, etc..... Color printers, on the other hand, are not RGB devices, but subtractive color devices (typically CMYK color model).
This article discusses concepts common to all the different color spaces that use the RGB color model, which are used in one implementation or another in color image-producing technology.......
Some more background info: In 24 bit RGB images, 8 bits (1 byte) are assigned to each colour. In Decimal they can range from 0 to 255 giving us 16777216 (256 x 256 x 256) possible colours. An additional 8 bits is sometimes used for alpha channel (transparency) so they may also be called 32bit images.
