RGBThe RGB colour model is an additive colour model in which red, green, and blue light are added together in various ways to reproduce a broad array of colours. The name of the model comes from the initials of the three additive primary colours, red, green, and blue.

RGBCMYK

The CMYK colour model (process colour, four colour) is a subtractive colour model, used in colour printing, and is also used to describe the printing process itself. CMYK refers to the four inks used in some co-lour printing:cyan, magenta, yellow, and key (black).

Refers to a method of specifying and print-ing colours in which each colour is printed with its own ink. In contrast, process colour printing uses four inks (cyan, magenta, yellow, and black) to produce all other colours. Spot colour printing is effective when the printed matter contains only one to three different colours, but it becomes prohibitively expensive for more colours.

SPOT COLOUR

Duotone is a halftone reproduction of an image us-ing the superimposition of one contrasting colour halftone (traditionally black) over another colour halftone. This is most often used to bring out middle tones and highlights of an image. The most com-mon colours used are blue, yellow, browns and reds.

MONOCHROME

Monochrome describes paintings, draw-ings, design, or photographs in one colour or shades of one colour. A mono-chromatic object or image has colours in shades of limited colours or hues.

Hexachrome Hexachrome was a six-colour printing process designed by Pantone Inc. In addition to custom CMYK inks, Hexa-chrome added orange and green inks to expand the colour gamut, for better color reproduction. It was there-fore also known as a CMYKOG process. Hexachrome was discontinued by Pantone in 2008 when Adobe Systems stopped supporting their HexWare plugin software.
