According to this method, upon reception of a color transform (T 2 ) associated with a main sequence (S 2 ), a transition sequence (ST 1-2 ) is generated from successive images of this main sequence such that the first image of this transition sequence is an image received after reception of this color transform (T 2 ), transition color transforms associated with images of said transition sequence (ST 1-2 ) are generated by blending a color transform (T 1 ) associated with a previous main sequence (S 1 ) or no color transform (U) with the second color transform (T 2 ), and each image of this transition sequence (ST 1-2 ) is processed using the transition color transform associated with said image.
