The most relevant factors between climate environment and architectural color are daylight and temperature. To refine the urban color system from the natural environment, we should use objective and scientific technological means, especially the climate analysis and climate adaptive design method. We mainly focuses on the temperature and light conditions in urban climate environment, explores two core technologies: 1) Urban color recommended chromatographic calibration technology based on temperature conditions; 2) The method of guiding architectural color design by using light climate effect.
