ABSTRACT:
An apparatus is disclosed with which a graphics designer can select an exact color to be shown on a video display device. The apparatus includes a control element movable in a region having at least two geometrical dimensions, each position in the region corresponding to a different color. If the region is only two-dimensional, the color element position defines two of the three independent variables needed to define the desired color, and the third is controlled independently.
