1. In a tristimulus color monitor (i.e., CRT) that employs phosphors excited (driven) by one or more electron beams, the process of controlling the beam(s) to ensure that the individual phosphors representing the color elements within each pixel are properly driven so that (a) within a given pixel there is a proper color balance to ensure the illusion of white, and (b) there is no spillover to adjacent pixels, causing false colors. 2. An analogous process applied to other types of color displays; e.g., a projection system using three spatially separated monochromatic CRTs, each generating a different color, and in which the three projected color images are superimposed on the projection screen, by means of off-axis optics, to achieve the illusion of white. 3. The calibration process performed to achieve the required proper color balance. 4. The result of such a calibration process, or the degree to which the ideal result is achieved.
