The present principles are directed to a method and device for region mapping from a first color region to a second color region. The method comprises a hue alignment angle θ of the preserved key color (prsv_color K0 ) and the key color (color K0 ) for each key color (color K0 ) of at least three key colors to define the preserved and rotated regions. K0 ); And performing a hue mapping of the current color from the first color area to the second color area, wherein the current color is in the preserved area defined by the preserved key color prsv_color K0 . If the hue mapped current color is immutable and the current color is outside the preserved area, the hue mapped current color is the hue alignment angle (θ K0 ) and preservation of two adjacent key colors of the current color (rotated gamut). Is calculated from the calculated area.
