Variation of Perceived Colour Difference Under Different Surround Luminance

With the wider availability of High Dynamic Range (HDR) Wide Colour Gamut (WCG) content, both consumers and content producers have become more concerned about the preservation of creative intent. While the accurate representation of colour plays a vital role in preserving creative intent, there are relatively fewer objective image and video quality assessment methods that are available which consider the colour quality. This paper will study the effect of surrounding luminance on perception of a colour stimulus, specifically, whether the perceptual uniformity is preserved in colour spaces and colour differencing methods as the surrounding luminance changes. The work presented in this paper provides important information and insight required for the future development of a successful colour quality assessment model.
