The metallic emotional equation for coloured metallic paints was developed on the basis of two experimental results. Experiment 1 involved measuring metallic paint appearance, and a multiangle spectrophotometer was used for measuring the appearance parameters of metallic coating samples under multiple measuring angles. In Experiment 2, observers were asked to visually assess coloured metallic samples under directional and diffuse light conditions. The observers assessed the test samples, illuminated from the top, from three observation angles. Principal component analysis was performed to analyse the observers’ emotional responses. Finally, the metallic emotional models consisting of the expensiveness model and fashion model were constructed.

The impact of viewing conditions on observer variability for cross-media colour reproduction / Yoon Ji Cho in COLORATION TECHNOLOGY, Vol. 135, N° 3 (06/2019)  

[article]  inCOLORATION TECHNOLOGY > Vol. 135, N° 3 (06/2019) . - p. 234-243 Titre : The impact of viewing conditions on observer variability for cross-media colour reproduction Type de document : texte imprimé Auteurs : Yoon Ji Cho, Auteur ; Guihua Cui, Auteur ; Ronnier Luo, Auteur ; Kwanghoon Sohn, Auteur Année de publication : 2019 Article en page(s) : p. 234-243 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Colorimétrie Métamérisme vision des couleurs Index. décimale : 667.3 Teinture et impression des tissus Résumé : This study investigates observer metamerism in cross-media colour reproduction (CMCR) between monitor and physical colours. An LCD display was placed inside a viewing cabinet. The cabinet had a mid-grey interior. Observers were asked to match a colour displayed on the monitor to a printed colour patch, which was also inside the viewing cabinet in two configurations, one consisting of two samples separated by a hairline gap (Configuration 1), and the other consisting of two samples separated by a large gap (Configuration 2). Eleven observers were asked to first match the background colour and then 10 test colours for each configuration, and this was repeated five times. The observers' variability results showed little difference between inter- and intra-variability, and between the two configurations. Comparing the observers' results with the CIE 1964 standard colorimetric observer, Configuration 1 and Configuration 2 each showed similar agreement. In both configurations, the results of observer variability were smaller than those obtained by Oicherman et al. in 2008. In addition, each configuration's results showed better agreement with the CIE standard colorimetric observer than Oicherman et al.'s results. This implies that both configurations, one with two samples having a hairline gap and with two samples separated by a large gap in a viewing cabinet, could be recommended for future CMCR systems. However, if choosing between the two, then Configuration 2 is recommended rather than Configuration 1.
