In color graphics displays, the colors generated are not repeatable from terminal to terminal. In the technique disclosed, color correction tables are stored by each display and accessed when a particular display is attached to a host. In order to display specified colors, initial comparison with a standard set of colors is required. The correction tables depend on phosphor color and the gamma curve of each display. Correction for the former is stored at the factory and for the latter, which may vary with time, by user set-up.
