RGB
The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
CMYK
The CMYK color model (process color, four color) is a subtractive color model, used in color printing, and is also used to describe the printing process itself. CMYK refers to the four inks used in some color printing:cyan, magenta, yellow, and key (black).
Spot Colour
Refers to a method of specifying and printing colors in which each color is printed with its own ink. In contrast, process color printing uses four inks (cyan, magenta, yellow, and black) to produce all other colors. Spot color printing is effective when the printed matter contains only one to three different colors, but it becomes prohibitively expensive for more colors.
Duo Tone
Duotone is a halftone reproduction of an image using the superimposition of one contrasting colour halftone (traditionally black) over another color halftone. This is most often used to bring out middle tones and highlights of an image. The most common colors used are blue, yellow, browns and reds.
PMS Pantone Matching System
A standard set of colors, with each color specified by a number. The Pantone colors can be further broken down into a color separation used by professional printers to calibrate color reproduction.
Monochrome
Monochrome describes paintings, drawings, design, or photographs in one color or shades of one colour. A monochromatic object or image has colors in shades of limited colours or hues.
Hexachrome
Hexachrome was a six-color printing process designed by Pantone Inc. In addition to custom CMYK inks, Hexachrome added orange and green inks to expand the color gamut, for better color reproduction. It was therefore also known as a CMYKOG process. Hexachrome was discontinued by Pantone in 2008 when Adobe Systems stopped supporting their HexWare plugin software.
