Abstract  Abstract

The present principles relate to a method and device for gamut mapping from a first color gamut towards a second color gamut. The method comprises obtaining a preserved key color (prsv_color K0) and a hue alignment angle (Æ K0) of the key color (colorK0) for each key color (colorK0) of at least 3 key colors to define a preserved gamut and a rotated gamut; and performing a hue mapping of a current color (color) from the first color gamut towards the second color gamut wherein in case the current color (color) is in a preserved gamut defined by the preserved key color (prsv_color K0) the hue mapped current color is unchanged and in case the current color is out of the preserved gamut the hue mapped current color is calculated from the hue alignment angle (Æ K0) of two adjacent key colors of the current color (rotated gamut) and from the preserved area.
