| Abstract |
The aim of this study is to analyze the emotion adjectives for light emitting diode(LED) light colors using a twofold adjective image scales from Kobayashi and I.R.I. A set of psychophysical experiments using category judgment was conducted in an LED light color simulation system, in order to evaluate each emotion scale coordinate for those test light colors in both adjective image scales. In total, 49 test light colors from a combination of 6 color series were assessed by 15 human observers. As a result, Kobayashi adjective image scale clearly expressed to emotion adjectives of ‘Dynamic’, ‘Casual’, ‘Chic’, ‘Cool-casual’, ‘Modern’, and ‘Natural’ for different hues. In contrast, I.R.I adjective image scale expressed only 2 adjectives of ‘dynamic’ and ‘luxurious’ for the all hues. |
