"The water is cold and the pool is clear, and the smoke is purple." The Preface to Wang Tengting by Wang Bo, a poet in the Tang Dynasty, describes the beauty of color changes around Wang Tengting. These two sentences are not limited to the static picture color, but focus on the color change of mountains and rivers: the water in the cold water pool is clear because of the retreat of accumulated water; The mountains in the evening are purple because of the twilight. The former sentence is elegant in color, while the latter sentence is strong in color. On the contrast of colors, it highlights the characteristics of autumn scenery, and is praised by predecessors as "writing the scenery in September".
