The Effect of Display Gamut Volume on Image Preference
  DOI :  10.2352/CIC.2007.15.1.art00038  Published OnlineJanuary 2007

Similar psychophysical experiments were performed at the Munsell Color Science Laboratory (MCSL), Rochester Institute of Technology, and at the Sony Corporation, Tokyo, in collaboration to determine observer preference as a function of color gamut volume as simulated using a Sony prototype, extended gamut, LED backlit, LCD video display. In both experiments, the overall results indicate preference was virtually indistinguishable above a color gamut volume ratio 0.8 times that of the full, extended gamut of the display. However, when the coarser MCSL data was subjected to a cluster analysis, sizable scene dependencies were revealed, and while the highly colorful scenes followed the overall result, preference for those scenes containing flesh tone clearly benefited from higher color gamut volume as did certain outdoor scenes. Because of these dependencies, finding an optimal color gamut that fits all may not be advisable. Instead, an extended color gamut might be better utilized by rendering object color to less than a full gamut leaving room for producing those portions of the scene that extend beyond object color offering a richer video experience.
