Abstract:
With the measurement of reflection spectrum and the experimental measurement of illumination observing angle, color temperature of light source, effects of field viewing angles, it is found that the color of facing materials have relation to light incidence and observing angle. The chroma number varies with the changing of light incidence and observing angle based on the features of facing materials. The chroma number has more fluctuation with the angle close to mirror reflection direction while it is more steady with other angles. Besides, the mirror reflection phenomenon is not obvious for subbrightness facing tile. The color temperature of light source affects material color and the chroma number varies with the incidence changing, etc. All of these have provided fundamental for quantitative study of architecture color design.
