  Model color space RGB   (Site not responding. Last check: 2007-10-13)
Model RGB is one of the first practical models of area of colors and contains the recipe for creation of colors.
This is the model resulting from the receiving specifities of eye and it is based on fact that the impressions of almost all the colors in eye can be evoked by mixing in the fixed propotions of three selected clusters of light of the properly chosen width of spectrum.
Model RGB defines in the evident manner that what the intensity is but for the individual components R,G,B. Namely, the values of components RGB describe individually the intensity of the given basic color as a number of partition from 0 to 1 and do not subject this value to the two remaining components.

 RGB color model - Biocrawler   (Site not responding. Last check: 2007-10-13)
The RGB color model utilizes the additive model in which red, green, and blue light are combined in various ways to create other colors.
One common application of the RGB color model is the display of colors on a cathode ray tube, liquid crystal display, or plasma display, such as a television or computer's monitor.
Instead, video RGB uses a convention with scaling and offsets such that (16, 16, 16) is fl, (235, 235, 235) is white, etc. For example, these scalings and offsets are used for the digital RGB definition in CCIR 601.

Bruce RGB: A version of the RGB color model with an expanded color space developed by Bruce Frasier, a well-known color consultant, in answer to the rising demand for color integrity, color management and color profiling not met by the smaller color space standard defined by sRGB.
Color Correction: The process of normalizing, changing or enhancing the colors in a digital image to achieve the effect, either of realism or of an artificial effect, which the artist or printmaker wishes to achieve from the final print.
It is the smallest color space defined by the RGB color model, thus guaranteeing accurate color data between unpredictable devices.

 Class RGBImageFilter
Specifies a method to convert a single input pixel, whose value is specified in the default RGB color model (II-§2.1.9), to a new pixel value also in the default RGB color model.
Otherwise, the method converts the buffer of byte pixels to the default RGB color model (II-§2.1.9) and passes the converted buffer to the filterRGBPixels (II-§2.9.7) method to be converted one by one.
Registers two color model objects for substitution: If the oldcm is the color model during any subsequent call to either of the setPixels methods (§2.9.9, §2.9.10), the newcm argument is substituted and the pixels passed through unmodifed.

 Serif Printing Resources - Color Models
RGB is typically used during the design process and CMYK is typically used during the print process, so knowing how they are different—or how to get them working together somehow—can help you aim for accurate color reproduction rather than be metaphorically blind, metaphorically, to the colors used in your design.
RGB is the color model used for devices that create colors using light e.g.
The RGB color model is called an additive model, which relates to the fact that we’re perceiving color as a mixture of discrete wavelengths of light transmitted directly from several sources—for example, from the red, green, and blue phosphors in a monitor screen.

 Color Management: Color Models, Color Spaces and Color Profiles - Photo Tips @ Earthbound Light
A typical color in RGB is represented by three numbers between 0 and 255, one for each of the red, green and blue components of the color.
Thus, a color space differs from a color model in that it maps specific values to specific colors while a color model only determines that the values will be the red, green and blue components (or whatever) without saying how much of any given component is needed to get what specific result.
It does this by mapping colors in the color space it represents to colors in an internal color space (usually CIE LAB or CIE XYZ but this is beyond the scope of this article) used by the Color Management System (CMS) embedded in your operating system or other software.

The RGB color model is an additive color model based on the human eye perception of colors.
These components are the amounts of red, green, and blue light measured in values ranging from 0 to 255, and they are combined in varying intensities to produce all other colors in the RGB color model.

IDL determines colors to display differently based on whether the destination object uses an Indexed or RGB color model, and on whether the physical destination device supports an Indexed or RGB color model.
If the physical device uses an Indexed color model, the RGB triple is mapped to the index of the nearest match in the device's color lookup table.
If the physical device uses an Indexed color model, the RGB triple retrieved is mapped to the index of the nearest match in the device's color lookup table.

 theWhiteSite: Computing: VB: The HSB Color Model
The name comes from the fact that each screen color is created varying the intensities of the Red, Green and Blue light beams that exist inside the monitor.
It certainly was just a matter of varying the intensities of each light beam so we would get a linear pattern of color shades where all the Reds would be grouped together, followed by all the Greens and, finally, all the Blues while the missing colors would be placed between each of these base shades.
Saturation: A colored spot can have a variation on the amount of color applied to it, that is, how vivid the color is. This is given by a percentage, where 0% means no color (White) and 100% means "normal" (very vivid).
