Abstract :
[en] The information we receive from the urban landscape is triggered and defined by the sense of sight, in other words by visual sensations. Colour is a fundamental component of the visual sensations: it allows us to identify objects with the contrasts that defines the form and it helps to structure the urban environment. As an attribute of the urban morphology, colour informs us about the status and history of a place, through relations of integration, dominance, fragmentation, homogeneity or heterogeneity that can be observed between its built components. Moreover, additionally to functional roles, colour can promote heritage values through a collective identity and besides marking our eyesight out with signals, colour makes sense in our visual environment, through a semantic function. Public authorities are aware of the impact of colour as a factor that can influence the image and attractiveness of cities, and in many European countries the principles of territorial governance seek the valorization of specific and local colour palettes which are considered to belong to the cultural heritage of the city or the region. In this regulatory perspective, several municipalities in Europe use chromatic charts as guidance tools in order to preserve the dominant local tones. The main purpose in a colour regulation is most of the time to harmonize buildings in a territorial area. This need for harmonization, standardization, which is equivalent to morphological consistency for many, is often considered to be essential for maintaining the urban townscape character. Thus in China, the concept of "urban colour" is becoming increasingly important in the field of planning to make an elegant urban environment. In the context of rapid economic growth of the country, many Chinese cities, mostly located in the eastern part of the country, conduct research and implement specific tools such as urban colour plans. These tools allow to continue the urban colour context, in a way of historical heritage based on the dominant colour, essentially to control and guide the development of new construction zones. The aim of this paper is to highlight the main similarities and differences between the European and the Asian politics concerning the management of the urban colour: although they developed on the same theorical base (specifically the “Geography of Colour” founded by Lenclos), they diverge from the point of view of purpose. The European approach is focused on the preservation and maintenance of the morphological specificities of urban tissues in terms of local colours, while in China, where built heritage tends to disappear in the urban regeneration under the real estate pressure, tools for the colour management are used mostly for the construction of new cities in order to keep the spatial coherence. The paper is illustrated with several European and Asian examples of concrete cases from both scientific and professional publications.
