What does the Ou & Luo colour-harmony work report (stimuli, observers, the model's structure, cross-country agreement), and what is open for me to read?

The open conference paper by Ou, Luo and Cui (Leeds, 2008) summarises five experiments: 1431 two-colour pairs from 54 CIELAB colours rated by 17 observers on a categorical scale produced a three-term additive harmony model (chromatic, lightness and hue effects); for three-colour combinations with 14 area/sequence layouts, harmony predictions by averaging pair scores reached r=0.81 (15 Chinese observers). Cross-country agreement across six countries (123 observers) was high for warm-cool, heavy-light and active-passive and low for like-dislike (Spanish group differing), but harmony itself was not a scale in that experiment. The original 2006 article is closed access; only its abstract was read.

The original 2006 article is closed access; only its abstract was read. Curator qualifications: Verified the observer counts, stimulus counts and correlations. The cross-country item concerns semantic scales; harmony agreement across countries is not reported, as the candidate says. The 0.85 confound vs S&P's separable-harmony result is a genuine methodological disagreement. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
