Abstract: The introduction of high-dynamic-range (HDR) color spaces and ultra-high-definition's (UHD) wide-color-gamut (WCG) color space in television creates a need to match colors on HDR and WCG displays with colors on conventional high-definition (HD) displays. Many contemporary color conversion methods that apply to conversion from HD to standard definition (SD), and color conversion methods mandated by current television standards, fail to produce a good color match when converting colors from the HDTV color space to HDR or WCG color spaces. This impairs the quality of HDTV contributions to HDR and UHD productions, as well as the quality of distribution of programs originating in HDR or UHD to HDTV viewers. This paper illustrates the color errors caused by the application of several of these conversion methods, and recommends one method, using display-referred colorimetry, for better color matching between narrow-gamut, wide-gamut and high-dynamic-range displays.
