Estimating visual difference between reproduction gamuts: moving our pilot study from the lab to online delivery
High, Gregory Paul; Nussbaum, Peter; Green, Philip John (Chapter, 2021)Images reproduced for different output devices are known to be limited in the range of colours that can be reproduced. It is accepted that reproductions made with different print processes, and on different substrates, ... -
The Helmholtz-Kohlrausch effect on display-based light colors and simulated substrate colors
High, Gregory Paul; Green, Philip John; Nussbaum, Peter Stefan (Peer reviewed; Journal article, 2023)The Helmholtz-Kohlrausch (H-K) effect is investigated in relation to light colors of every hue, including those typical of print substrate colors that might be simulated on a graphic arts display. A method of adjustment ... -
The impact of the Helmholtz-Kohlrausch effect on the appearance of near-white paper colours
High, Gregory Paul; Green, Philip John (Chapter, 2021)This paper investigates the impact of the Helmholtz-Kohlrausch effect on near-white substrate colours. As the luminance of the test colour (or its simulated reflectance in a softproof setup) approaches that of the adapting ... -
Quantifying and Evaluating Colour Appearance Models based on Helmholtz Kohlrausch Effect
Ullah, Ehsan; High, Gregory Paul; Green, Philip John (Chapter, 2022)The brightness sensation of a colour source depends in part on colour purity, and this colour appearance phenomenon is defined as the Helmholtz-Kohlrausch effect. With the recent advancement in HDR and WCG displays, greater ...
