Color is a powerful and attractive aspect of our experience of the world, which shapes the perception, interpretation, and memories of everything seen. Color therefore provides <p>an important dimension in visual communication, which when used well may greatly enhance the effectiveness of a message, but when used badly may substantially impair it.</p> <p>Computer graphics and computer-generated imagery constitute another medium for visual communication, to be added to a list that includes drawing, painting, printing, photography, cinema, and television. In every case the effective use of color depends not only on the affordances (the intrinsic strengths and limitations) of the particular medium but also on human factors and the context in which the display is viewed. Choice of graphic color palettes and handling of image color rendering must be based on a user-centered design perspective, considering all aspects of the communication. It follows that no strict rules can be laid down for the use of color in computer graphics, because what works well in one case may be detrimental in another. Nonetheless, guidelines prove useful when choosing colors for different purposes.</p>
