Abstract

The present invention varies the highlight color of a highlighted display area such that the salience of the highlighted display area remains constant to a user as the highlighted display area varies. A perceptual highlight color is determined based upon the total amount of highlighted display area and the background color of the non-highlighted display area and applied to text selected to be highlighted by a user as well as to text already highlighted on the display. In other embodiments, the perceptual highlight color can be based upon the total amount of highlighted display area and the text color of the text in the highlighted display area, and the total amount of the highlighted display area, the background color of the non-highlighted display area, and the text color.
