The aim of this paper is twofold: 1. To summarise the 'state of the art' on conflicting experiences of colour space based on psychological and architectural interpretations. 2. The presentation of the preliminary findings of on going longitudinal studies at Oxford on colour attitu des to full scale colour spaces by architects and laymen. Conflict is considered at several levels of conceptuali zation. Conflict within the individual depending on his physiological and psychological state. Conflict within a group in their experiencesand attitudes to colour spa ces. Conflict within a group between personal evaluation and social evaluation. Conflict between groups in their perception and responses to colour. Architects' colour taste will be compared to the taste and aspirations of laymen. Conflict as a result of differences due to age and lex. Conflict arising as a result of the architectural di lemma: What we know about colour as scientists and psycho logists and what we do as artists and architects. The distinction will be made between synchronic conflict apparent conflict at any given time - and diachronic con flict - brought about through changes mainly the time factor but also taste, habituation.
