On the use of layout, colour and typography on visual display terminals

Some guidelines are given to meet the observed need for rules about the use of colour and typography on multicolour display screens so as to create texts of optimum legibility. Examples of videotex pages are used to illustrate right and wrong layouts, applications of colour and letter type. The guidelines can be generalized to cover other types of display, such as those used in personal computers and, to a more limited extent, to the use of graphics instead of text. Finally, figures are given on the general public's subjective appreciation of some alternative display layouts .
