A method for achieving color-appearance matching for an image viewed in different surround conditions, the method comprises the steps of forming signals representing an original image; and mapping the original image signals through a transformation that alters image luminance contrast by a factor of substantially 1.01 to 1.15 for an original image viewed in a light surround to a reproduced image to be viewed in an average surround; substantially 1.01 to 1.22 for an original image viewed in a light surround to a reproduced image to be viewed in dim surround; substantially a range of 1.01 to 1.29 for an original image viewed in a light surround to a reproduced image to be viewed in an dark surround; substantially a range of 1.01 to 1.11 for an original image viewed in an average surround to a reproduced image to be viewed in an dim surround; substantially a range of 1.01 to 1.22 for an original image viewed in an average surround to a reproduced image to be viewed in an dark surround; and substantially a range of 1.01 to 1.21 for an original image viewed in an dim surround to a reproduced image to be viewed in an dark surround for achieving color-appearance matching of a reproduced image to the original image.
