Television Receiver White Color: A Comparison of Picture Quality with White References of 9300 K and D6500

Color television receivers in the U.S.A. generally have a white color approximately equivalent to the appearance of a black-body at 9300 K, or higher. The white reference of a studio monitor is specified at D6500. In connection with the study of color television variability being conducted by an Ad Hoc Committee (AHCCTS) of JCIC, the question was asked, “Is a viewer's tolerance to color variation different for the two display situations?” To answer this question observers were asked to rate for quality pictures having a wide gamut of color variation originating from photographic slides, presented through telecine separately on two receivers adjusted to the two display conditions. Observers ranked the pictures displayed on the D6500 receiver consistently higher in quality than the pictures displayed on the 9300-K receiver. — The conclusion that viewers prefer pictures displayed at a white reference of D6500 to those referenced to 9300 K prevented obtaining an answer to the original question on tolerance to color variability, but in itself is a more important fact bearing on the choice of a white reference for television receivers.
