ABSTRACT:
An interface system allows a user to select and control colors used in graphic images generated by a computer system. The interface system employs graphical representations of the hue, chroma, and lightness combinations capable of being rendered by a computer graphics system. In a preferred embodiment, the graphical representation includes a one-dimensional graph (40) depicting the range of hues and a two-dimensional graph (42) depicting the range of chroma and value combinations available for a selected hue. The graphical representations are preferably rendered in accordance with a Hue-Value-Chroma ("HVC") color space (90) having a high degree of perceptual uniformity.
