Abstract
A color printer control system comprising a user interface for shifting color hue. A control panel display includes an illustrative representation such as a color spectrum bar for suggesting a color range for both the input document and the output document. The user interface has a selective control such as a slide bar including an indicator of a user preference relative to the color reference bar. The position of the slide bar represents the hue shift input by the user. A dynamic image representation, such as a photograph, concurrently adjusts its hue in accordance with adjustment of the color slide bar and the user command. The dynamic image shifts color hue to provide a more accurate indication of the effects of hue shift to the user.
