Abstract
There have been many researches regarding color emotion because of the characteristic of LED illumination which is able to make various colors. Especially, the color of object could be changed by different spectral distribution of LED illuminations having same color temperature. In this research, the color emotion study was conducted under the 4 different lighting conditions which have same illuminance levels and color temperatures, but different spectral distributions. Total 30 people participated and each participant evaluated 22 test colors. To evaluate test colors" emotions, ten adjective sets were used and those were ‘Warm-Cool’, ‘Heavy-Light’, ‘Modern-Classic’, ‘Clean-Dirty’, ‘Active-Passive’, ‘Hard-Soft’, ‘Tense-Relaxed’, ‘Fresh-Stale’, ‘Masculine-Feminine’, ‘Like-Dislike’. Findings of the study are as follows: Though CIELAB values were changed as color rendering of illumination changed, there were no significant emotion shifts. It was found that ‘Warm-Cool" and "Masculine-Feminine" are mostly affected by CIELAB hue angle. CIELAB L* dependent adjective set was "Heavy-Light". CIELAB C* dependent adjective sets were ‘Heavy-Light", "Active-Passive", and "Fresh-Stale". Also the performances of previous color emotion models, Ou, Sato and Xin-Cheng, were compared. The results showed that Ou model showed the highest performance of explaining the experimental data in this research.
