Description

ABSTRACT:
A window for use in a monochrome LCD or gas plasma display is provided with a "Color Finder" button for identifying each of 16 (or 64) colors to be displayed. By activating a button in the window, the indicated gray scale for that color is temporarily inverted so that it oscillates between its current value and its most opposite value. This technique "flashes" the associated shade of gray on the screen, thereby informing the user that the color is in use on the screen and pinpointing just where the color is being displayed. Consequently, this invention allows the computer user to limit gray scale adjustments only to those that are needed.
