a method for transforming color gamut from a first color space to a second color space , includes dividing the first color space into a first plurality of regions in an objective space ; dividing a subset of the second color space into a second plurality of regions in the objective space ; mapping a first region of said first plurality into a first region of said second plurality substantially without change ; mapping a second region of said first plurality comprising an upper gamut of the first color space into a complementary second region of said second plurality ; and mapping a third region of said first plurality comprising a lower gamut of the first color space with a gamma correction into a complementary third region of said second plurality .
