The paper discusses the significance of colour design of sports facilities from the point of view of creating psychophysiological comfort for visitors. The study was conducted in two phases. The first stage consisted of a survey in the form of a questionnaire, during which the value of comfort for two groups of respondents totalling 289 persons was determined, as well as the importance for respondents of these groups of basic indicators of comfort of sports facilities. The results of the study showed that the comfort, interior styling and colour design of a sports facility are important and not of last importance for different categories of visitors to sports facilities. The second stage was carried out by an expert assessment method (the Delphi method), during which the colour design of the sports training block (STB) «Snezhnyi» (cluster «Sopka», Krasnoyarsk) was evaluated in terms of the level of psychophysiological comfort to be created among users of services. The result of the conducted expert assessment showed that the level of psychophysiological comfort created by the color decoration of STB «Snezhnyi» is evaluated as «close to high» and «high». Research has shown that color solutions used in the design of sports facilities can be important in creating psychophysiological comfort for visitors, and, therefore, can be used as one of the success factors in developing a marketing strategy for sports facilities.
