This article presents a user-oriented protocol that can be used to characterize chromatic attributes of an urban area. A need for both affordable and reliable assessment method of color has been observed in the field of urban design. The challenge is to provide statistical answers to these two questions: how is color organized, how does it develop its own structure in the city? The main purpose of the research is hence to investigate mean color types within the city via the implementation of a characterization tool; an urban area of the four main classes (historic center, periurban housing districts, working-class neighborhoods, and commercial zones) being characterized by a specific color palette, or a layout of specific color types. The developed instrumentation allows the assessment of the homogeneous and consistent features of an urban district. Their characterization protocol was tested through an application to several streets of the city of Liège (Belgium). [less ▲]

Colour is an essential component of urban landscapes that inform us about the status and history of a place, through relations of dominance, integration or uniformity that can be observed between its built components. It can be shown that many traditional cities appear to be « chromatically polynuclear » in Europe and that each epoch, each type of urban area, each city is characterized by its own colour palette, which can be more or less homogeneous. Still the urban mutations observed in the second part of the 20th century generated a significant increase in the entropy of contemporary extentions of cities, which induced a loss of meaning and coherence by dislocating permanent structures set up in the past that maintained some integrity of urban landscapes. City entrances for instance, where old buildings mix with commercial equipment, show an unprecedented heterogeneity in their colour palettes. Few studies have focused on the description of these emerging configurations. Their complexity both in formal and chromatic aspects is certainly a difficulty from the perspective of their characterization. This can be explained by the lack of tools for an objective analysis of colour palettes in an urban environment. Given this lack of both affordable and reliable assessment method of colour that has been observed in the field of urban design, the research presents the implementation of a tool that can be used to characterize chromatic attributes of an urban area. The challenge is to provide statistical and quantitative answers to these questions: how is colour organized, how does it develop its own structure in the city? How can colour appear as an indicator of homogeneity and spatial coherence? As colour can be represented in a tri-dimensional space, we use a k-means statistical clustering technique, based on a data partitioning algorithm, to produce a chromatic classification of building facades. Once the chromatic categories are defined through the developed assessment method, the question of spatial coherence is investigated using Shannon entropy. Our method was tested through an application to several urban fragments of the city of Liège (Belgium) and the research highlights the differences between historic urban areas (historic center, 19th century developments) with new urban configurations (city entrances, commercial and periurban zones).

The aim of this paper is to present a user-oriented protocol for the characterization of colour attributes in an urban fragment. The challenge is to provide quantitative answers to these questions: how is colour organized? How does it develop a structure in the city? Our research investigates stable colour typologies. The obvious lack of effective tools for the chromatic assessment in the field of urban design was the main motivation of this research. The protocol is illustrated within the study of the “rue des Anglais” in Liège (Belgium) and the stability of the method is conducted through a series of validations. [less ▲]

A growing need for objective assessment of colour has been observed in recent years in the field of urban design. In contrast to other building attributes (shape, size or location), which are easy to specify, urban design codes generally define expected chromatic attributes of building façades through indirect regulations considering materials. Some municipalities propose colour charts as guidance tools for urban regulation which present some disadvantages. This obvious lack of affordable instruments in a purpose of characterization or regulation was the main motivation of this research. The aim of this paper is to present a user-oriented protocol which can be applied to characterize chromatic attributes of an urban fragment. The challenge is to provide quantitative answers to these two questions: how is colour organized, how does it develop a structure in the city? The main purpose of the research is hence to investigate stable colour typologies within the city; each urban area (historic center, suburban housing district, commercial zone, etc.) being characterized by a specific colour palette.
