ABSTRACT:
Methods and means are described for enhancing the visibility of small errors in color balance and color adjustments of images previewed for subsequent production. The visibility of color differences is enhanced by varying the color reproduction of a system in such a way that, for each color, the luminance and hue remain constant while the chroma is increased. The size of the increase in chroma is related to the magnitude of the initial chroma. This increase in chroma enhances the visibility of small color deviations and makes it much easier for an operator to decide whether an image is correct with respect to color balance.
