ABSTRACT:
In a feedback color control system for controlling the flows of two colorants used to color an article, a first error signal is generated as a function of deviations in the color saturation of the article from a desired saturation, and a second error signal is generated as a function of deviations in the hue of the article from a desired hue. The flows of the dyes are varied in the same sense in response to the first error signal and are varied in opposite senses in response to the second error signal.
