The use of colour in raster graphics

Abstract

Colour computer graphics covers a wide field of applications such as games, computer aided-design, image processing and digital terrain modelling. The traditional way of using colour in raster graphics systems, the RGB colour model, is not always acceptable to the user who finds it unnatural and difficult to use. These disadvantages can be overcome by the use of colour models that provide natural interfaces, such as the HSI, HSL and CNS colour models, or a uniform colour space such as the LUV colour model. This paper describes these models and discusses their use in colour assignment and other applications. Keywords: Colour, colour models, uniform colour spaces, colour in raster graphics.
