Abstract: The present invention relates to a color control system for controlling, in real time, the color of an article positioned on a moving carrier. The system comprises: an illuminating device configured to illuminate the moving article in successive illuminating cycles, each illuminating cycle comprising successively generating, at a given rate, a given number of lines of light having distinct spectral bands the lines of light being substantially perpendicular to the direction of movement; a detecting device configured to detect the light back scattered by the article successively illuminated by each of the lines of light, such as to generate for each dot of a given number of dots of an observation strip perpendicular to the direction of movement, a number of signals corresponding to the light back scattered by the dot; and a processing unit configured to determine at least one value representative of the color of the dot.
