RGB: All about digital camera color
We trust you had a happy holidays. This issue is devoted to one of the most elusive aspects of understanding digital cameras--how they reproduce color.
RGB (Red, Green, Blue) is a common way of representing colour in a digital image. The colour of each pixel is represented by three numbers, being the amount of red, green and blue light making up that colour.

RGB Histogram
CAMERA'S CORRECT EXPOSURE
It is pretty obvious that the camera's selected metering is not going to cut it with this midday beach image. The luminance histogram indicates that almost all of our tonality is left of midtones.
It's more difficult to analyze this particular range of color using RGB numbers. That's why we set up the second color readout to CMYK in the Info palette.
RGB Primary Colors -- Additive Color
Figure 1: RGB Additive Colors
Based on what has been covered so far, it will probably come as no surprise that the first set of primary colors is red, green, and blue.

RGB is one of the several color spaces available, RGB stands for Red Green Blue; it is an additive color space in which the colors, as light, are added together to achieve all the other various colors in the spectrum.

One way to reduce the space and time requirement is to use Adaptive Supersampling. This method takes advantage of the fact that very few pixels are actually on an object boundary, so only those pixels need to be supersampled.

This is how much RGB (Red Green and Blue) light the CCD has recorded. You can select each colour channel separately and adjust them until you get the correct overall colour you desire. Next you can 'saturate the image'.
RGB

If we give 256 steps (8 bits) to each of the RGB colors that create the color palette, these colors can be mixed in 16.7 million ways (256 x 256 x 256) to create 16.7 million color choices.
Viggiano found that white balancing in the camera's native RGB tended to produce less color inconstency (i.e., less distortion of the colors) than in monitor RGB for over 4000 hypothetical sets of camera sensitivities.
Elements (pixels) are coated alternately with RGB filters. This pattern may be in stripes or a mosaic. Some arrays have twice as many green elements as red or blue creating an apparently more detailed image because the eye is more sensitive to green.
