Abstract: A method for transformation of color values of an initial color space reproducible by a first technical device to color values of a target color space reproducible by a second technical device is provided. The method includes movement from one color space by conversion of color values to different color values in the basic color space and scaling by conversion to different color values in the basic color space. The method also includes conversion of color values of the initial color space to color values which are closest to the color value in the edge area of the target color space. The method also includes movement of color values located in an edge area of the target color space to the interior of the target color space by conversion as a function of the number of identical edge color values to color values on the same color variation plane.

Abstract: In order to provide a method for transformation of an initial colour space to a target colour space in which, in particular, detail losses and contrast losses are minimized, the present invention proposes a method for transformation of colour values from a an initial colour space to a target colour space, both of which are related to a defined basic colour space, in which case at least one plane in the colour spaces define a profile of the brightness from bright to dark, and planes running transversely thereto define colour variations, characterized by the following steps a) movement from the initial colour space and/or the target colour space by conversion of all the colour values of one of the two colour spaces to different colour values in the basic colour space, so that the initial and the target colour space are coincident with respect to at least one colour value located at the edge of a colour space, b) scaling of the initial colour space and/or target colour space by conversion of all the colour value
