CMYK vs RBG

CMYK:
CMYK stands for Cyan, Magenta, Yellow and Black.
CMYK is a colour model that is often referred to as four colour printing. According to this site, which is referenced at the end of the paragraph, CMYK is mainly used for offset printing, as well as full colour documents.

RGB:
RGB stands for Red, Green and blue. In some cases it can be quite difficult to convert CMYK to RGB, and vice versa.

RGB is a technique in which red, green, and blue are combined to produce different tones, such as yellow, cyan, and white.
