Color is one of the essential factors in architecture, as James B. Jordan said: “Color is inevitable, except for those who are color blind,” which means how to use color in architecture is of great significance. People tend to acquire perceptual knowledge of a material through color, shape and texture, where color occupies the most important position. People can identify a city that includes culture, classic by urban color. Furthermore, the functionality of color in architecture cannot be ignored. It helps bring a convenient and efficient lifestyle for citizens. Furthermore, successful urban colors improve public impressions, promote and attract visitors. However, the influence of color in architecture is not only positive, the blind pursuit of individuality can cause “color pollution”, as well as visual fatigue and confusion. To successfully design the way of using color, some points should be included: culture, landscape and function. Main body: According to Vastus Hastra (one system), color synchronizes and balances our energies and influences our lifestyle. For example, red reminds us of fire, power and energy. On the contrary, blue means water, freshness, melancholy. However, each color has its own special meaning in different countries, which means that the colors symbolize different cultures of cities or countries.

However, the Chinese believe that black represents that... the center of the paper....... Although physical geography and human geography are the main elements of color in architecture, the structure of the building also decides the distribution of colors. Symmetry and contrast are usually used in the design. The former currently consists of the same surface or form of colors, the latter chooses strong colors to strengthen the visual effects. With the emergence of deconstruction architecture, some architects tend to use multicomponent and fragmented elements in projects; colors also have these characteristics. The Imperial War Museum North is a representative of deconstruction architecture, the fragmented and dark color creates a serious atmosphere that simultaneously appeals to the function of the museum. Color in architecture requires a system consideration, in addition to the above-mentioned factors such as culture, geography, function and structure, other elements should be thought of.
