|The two main color spaces in Image processing are RGB and CMYK
The RGB color model relates very closely to the way we recognize color with the R, G, and B receptors in our retinas. It’s the fundamental color model used in television or any other medium that projects color with RGB which uses additive color integration. Computers and web graphics use this basic color model but it cannot be used for print production.
Overlapping layers of varying percentages of transparent cyan (C), magenta (M) and yellow (Y) inks is laid down by the 4-colour CMYK model used in printing. A layer of black (K) ink can be added. The subtractive color model is used by The CMYK model.
