Abstract

In Human Computer Interface, graphics, icons, images and colours (screen) can be a powerful communication and attention getting technique. To understand how colours should be used in order to obtain the desired target on a screen, it is important to know about: user eye, how to choose the colours for categories of information, what the common meanings are, how to locate the colours on the screen, which the physical impressions are when the usability is verified. The order of colours, the foregrounds and the backgrounds, the number of colours, are all communication tools.
