Every city brings people different feelings with its different colors, shapes and characteristics.
A scholar pointed out that the gray walls, gray tiles and green trees in old Beijing constitute the keynote of Beijing's urban color, revealing the thick, simple and quiet cultural heritage of the ancient capital and setting off the magnificent royal style of the Forbidden City. The red tiles, red walls, blue sea and blue sky in the old city of Qingdao also fully show the elegance of this beautiful coastal city. Urban color is integrated with the environment and formed for a long time. Unity and harmony are very important.
Internationally, some countries use the theory of color seasons to design urban landscapes, and some cities have formulated urban architectural color plans, such as beige as the main color in Paris and khaki as the main color in London. At the same time, many theories of urban color construction with great international influence have been established abroad, such as the "color geography theory" of French color master Lancome on urban environmental color construction, which has contributed greatly to urban color construction.
Generally speaking, urban color planning in China lags behind urban construction. Because there is no unified architectural color standard and supervision and management, the application of color in the field of architecture is chaotic, which leads to the problem of visual pollution in many buildings in China and has a negative impact on the shaping of urban image. For example, graffiti often appears on the streets; Advertisers wantonly use strong stimulating and intrusive contrast colors, infinitely expand the advertising area and quantity, and seriously pollute the human environment. In particular, the advertisements of light boxes in front of stores have different shapes and strange colors, which not only destroy the colors of the original buildings, but also cause serious color pollution. Therefore, it is urgent to explore new strategies of urban construction planning to better promote the healthy and stable development of urban construction in China.
