A quantitative study on color emotions for double chromatic light in landscape illumination

For the results of early quantitative studies on color emotions can not be used in large-scale light environment, the quantificational method of color emotions for the large-scale landscape illumination environment was put forward. In a psychophysical experiment, 21 large-scale double chromatic stimuli on 20 chromatic-light emotional scales were assessed. The factor analysis identified two double chromatic-light emotional factors: activity and evaluation. The paper predicted double chromatic-light emotions by monochromatic-light emotions values in arithmetic mean way, and figured out that the successfully predicted emotions factors are all from activity factor. The paper discussed the factors of double chromatic light emotions to build a scientific and efficient method of predicting chromatic light emotions quantitatively.
