Summary:The color temperature and light color of nighttime lighting in a particular city is an important factor in determining its nighttime identity. To quantitatively analyze the nocturnal characteristics of Seoul, this study focuses on the light color of the lighting sources that used in the places included in the Seoul Night View 100 Photobook. As a result, the color temperature of white light in the surveyed places is in the range of 2,500~3,500K, of which 3,000~3,500K represents the highest proportion. In addition, the color temperature in the 2,500~3,500K range was found to be evenly distributed across the five surveyed regions. Apart from white light, blue color hue accounts for a high percentage in the monochromic light category, and the excitation purity was measured to be 71.6% on average. In addition, 46% of the buildings with monochromic light are in urban centers.
