Classification: CPC G  H | IPC G  H

Claim 1:
2. The method of color-measuring according to claim 1 further comprising determining the selected other color within the gamut boundary by:
determining an image-gamut of said digital image in an N-dimensional device independent color system, wherein N>1 and said image-gamut comprises color values of said digital image; and
determining a skeleton of said image-gamut, wherein said skeleton comprises a plurality of points which are determined by:
selecting a luminance-range for color values in said N-dimensional device independent color system;
determining a sub-image-gamut of said image-gamut, wherein said sub-image-gamut corresponds to said luminance-range and comprises color values which have a luminance in said corresponding luminance range; and
determining a color value in said sub-image-gamut as a point of said skeleton;

wherein said selected other color has a color value with a minimum color difference between said color value of said skeleton that is smaller than 3 ΔECIELAB,94.
