With the right software, anyone can create a colourful display on a computer. This practical guide explains how to use colour effectively - to communicate on screen, on different computers, or from computer to print. It abounds with advice on the techniques and equipment, design, faces and colour choices. The authors also give extensive information on how the eye sees colour, how we describe and model colour, and how the computer generates and displays it. To demonstrate the true impact of colour onscreen, the authors have also compiled a set of example illustrations available separately on disk.
