Several color models are currently in use. The three most common models are described below.
PANTONE: Colors are selected from the PANTONE Matching System and designated as C (coated) for glossy/coated materials or U (uncoated) for multi-purpose paper used in most printers.
CMYK: Print companies use the phrase "four color process" or CMYK (referring to Cyan, Magenta, Yellow and blacK). For programs without PANTONE models, this is the best substitute for printed materials. Each color value ranges from 0 to 100.
RGB: This model is best for projected images (television, computer or video screens). Colors are broken down into three components of light - Red, Green and Blue - and have values ranging from 0 to 255.
