Abstract: A method and systemof image processing on a computer, and a computer program product adapted for image processing, wherein a digital image of an article is improved into a computer, the digital image is colour-corrected, an internal palette is generated from a database of predetermined colour attributes and applied to teh colour-corrected digital image so as to generate a second digital image, and wherein a third digital image corresponding to the second digital image is generated, but replacing the predetermined colour attributes with vivid colour attributes. The present invention is of particular utility in the manufacture of dental prestheses from ceramics materials which substantially match a person's natural tooth colours.
