A Research on Use of Colors in Chinese Cityscape Zhenglei Dong Huanghe Science and Technology College, Zhengzhou, China zcc201201@qq.com Keywords: cityscape, colors, the spirit of the city, light and materials.
The use of light and materials in color design of cityscapes.
Therefore, the architectural materials as well as the science of light must be taken full consideration in color design to make the color of the city more harmonious.
At present the color design of cityscape in China is more influenced by architectural materials than the other traditional factors and the use of new materials will directly lead to a change of visual concepts.
What’s more, texture is another important consideration in choice of architectural materials to make buildings more sensational in tactile.

In [9] the method in processing functionally gradient material has been the subject of research in materials science, in the field of composite materials and ceramics.
