A method and apparatus for modifying colors in an image displayed on a display device by a computer controlled display system. The method includes selecting at least one color being representative of at least one pixel of the image, where the image is comprised by a plurality of pixels on the display device; determining the colorimetric values for the at least one color; selecting a second color and determining the colorimetric values for the second color; and modifying the colorimetric values of a plurality of pixels in said image such that for any given pixel of the plurality of pixels having colorimetric values being matched to the colorimetric values of the at least one color, then the colorimetric values of the given pixel are modified to match the colorimetric values of the second color. A method for the user selecting the at least one color and the second color is described. A method for the user to add to the selection of the at least one color also is described. The apparatus of the invention comprises a display device; a cursor positioning device; a plurality of smoothed, look-up tables to provide a selection of a region of a color space, which selection is representative of a portion of said image near the at least one color; memory for storing data representative of the region and a second color; and a data processing unit. The method and apparatus allow a selection and automatic modification of a group of colors while maintaining the relationship among the colors so as to appear relatively the same with respect to texture and tonality. 46
