Doctor of Philosophy (PhD) / The overall aim of this research was to examine aesthetic response to façade colour. Drawing on a range of theories and studies from environment-behaviour studies (EBS), Nasar’s (1994) probabilistic model of aesthetic response to building attributes provided a theoretical framework within which to examine patterns of response. Prompted by the Development Control Plan for Sydney Regional Environmental Plan: Sydney Harbour Catchment (NSWDOP, 2005), this research also linked its aims and methods to planning policy in Sydney. The main research questions focussed on whether changes in aesthetic response are associated with variations in façade colour; and whether changes in judgements about building size, congruity and preference are associated with differences in façade colour. A quasi-experimental research design was used to examine patterns of aesthetic response. The independent variable was represented by four façade colours in two classifications. An existing process, environmental colour mapping, was augmented with digital technology and used to isolate, identify and manipulate the independent variable and for preparation of visual stimuli (Foote, 1983; Iijima, 1995; Lenclos, 1977; Porter, 1997). Façade colour classifications were created from extant colour theories (including those of Albers, 1963; Hard & Sivik, 2001 and Itten, 1961). The façade colour classifications were further developed using F-sort and Q-sort methodology (Amin, 2000; Miller, Wiley & Wolfe, 1986; Stephenson, 1953). Ten dependent variables, linked to overall aesthetic response, were drawn from studies relating to environmental evaluation, building congruity and preference (Groat, 1992; Janssens, 2001; Russell, 1988; Russell, 2003; Russell, Ward & Pratt, 1981; Wohlwill & Harris, 1980). The dependent variables were presented in the form of a semantic differential rating scale and a sample group of 288 evaluated the visual stimuli. The Latin-square technique was used for the controlled presentation of visual stimuli. Factor analysis, correlation analysis and analysis of variance were applied to the data. The findings indicate that variations in aesthetic response are associated with differences in façade colour. Judgements about building size varied by up to 5% and buildings featuring contrasting façade colours were judged to be larger and more dominant. Judgements about a building’s congruity varied by up to 13% and buildings that featured harmonious colours were considered to be more congruous. Preference varied and harmonious façade colours were not necessarily preferred over contrasting façade colours. The outcomes from this research suggest that a new approach to façade colour within the context of planning policy may be appropriate. A model of façade colour evaluation is presented and, unlike current planning guidelines, the model allows for a participatory approach to façade colour evaluation and specification. The model allows for factors that may influence aesthetic response to façade colour (such as contextual, perceptual and idiographic factors) as well as variation in architectural expression with respect to façade colour.
