1. A method to build a color calibration transform for the color calibration of a second image capture device adapted for the capture of a specific scene, said color calibration being adapted to represent the captured colors of said scene in a specific output color space, wherein an output color transform is predetermined that is able to transform any set of device-independent color coordinates representing any color in a given colorimetric color space into a set of output device-dependent color coordinates representing said color in said specific output color space, wherein a first parametric color transform of a first image capture device is determined that allows the transformation of any set of 1st-device-dependent color coordinates resulting from the capture of a color by said first image capture device into a corresponding set of device-independent color coordinates representing the captured color in the colorimetric color space, said method comprising: clustering the colors of pixels of an image representative of said specific scene captured by said first image capture device into a plurality of color clusters, among said plurality, selecting a set of color clusters independently of a color checker chart, defining a set of calibration colors within said scene such that each calibration color corresponds to a different selected color cluster, by using said first image capture device, capturing each calibration color, resulting into a set of calibration 1st-device-dependent color coordinates for each calibration color, by using said first parametric color transform, calculation of a set of three calibration device-independent color coordinates for each set of calibration 1st-device-dependent color coordinates in order to represent each calibration color in the colorimetric color space, by using said second image capture device, capturing each calibration color, resulting into a set of calibration 2nd-device-dependent color coordinates for each calibration color, estimating a second parametric color transform such that any set of calibration 2nd-device-dependent color coordinates representing a captured calibration color is transformed into a calculated set of calibration device-independent color coordinates corresponding to the same calibration color, and building said color calibration transform by the concatenation of the second parametric color transform with the output color transform.
