The method comprises the steps of: —for each combination of a first and second illuminants, applying its corresponding chromatic adaptation matrix to the colors of a first image to compensate such as to obtain chromatic adapted colors forming a chromatic adapted image and calculating the difference between the colors of a second image and the chromatic adapted colors of this chromatic adapted image, —retaining the combination of first and second illuminants for which the corresponding calculated difference is the smallest, —compensating said color differences by applying the chromatic adaptation matrix corresponding to said retained combination to the colors of said first image.
