A method for harmonizing colors of an original image is disclosed. The method comprises: computing a saliency map of the original image, for each of a plurality of color harmonic schemes: determining a temporary harmonized image from the original image according to the current color harmonic scheme, computing a saliency map of the temporary harmonized image, comparing the saliency map of the original image and the saliency map of the temporary harmonized image, in order to obtain a saliency comparison result, computing a corrected color comparison result from colors of the original image, colors of the current color harmonic scheme and the saliency comparison result, selecting, as the harmonized image, the temporary harmonized image obtained with the color harmonic scheme minimizing the corrected color comparison result.
