1. A color calibration method performed by a processing system of a light-emitting display system having light-emitting elements (LEEs) and comprising a storage module, the method comprising:
performing a color measurement of a plurality of light-emitting elements (LEEs) of the display system;
determining color space values for the color measurement of said plurality of LEEs;
defining for said plurality of LEEs a first set of target colors in color space values;
defining for said plurality of LEEs a second set of target colors in color space values;
calculating a first calibration matrix using the color space values for the color measurement of the plurality of LEEs and the first set of target colors;
calculating a second calibration matrix using the color space values for the color measurement of the plurality of LEEs and the second set of target colors;
defining a matrix factor, the matrix factor being selectively chosen in relation to said first set of target colors and/or second set of target colors, as a real number; and
calculating a final calibration matrix, the final calibration matrix being defined by said first calibration matrix and said second calibration matrix, each being weighed using said matrix factor.
