Abstract

There are provided methods and systems for color correcting displays with different color gamuts. A method includes performing color correction on source picture content, using at least one of a non-reference type display having a non-reference color gamut and a reference type display having a reference color gamut. The performing step includes mastering the source picture content to provide mastered color corrected picture content for display on the non-reference type displays having a non-reference color gamut. The performing step further includes generating metadata for a color gamut mapping that color transforms the mastered color corrected picture content for display on reference type displays having a reference color gamut. The source picture content is mastered only for the non-reference type displays having the non-reference color gamut.
