The article examines the properties of the colored surface of the Art object as a means of creating a harmonious architectural environment. The question was raised about the relevance of increasing the comfort, functionality, ergonomics, environmental friendliness and aesthetics of the design of the architectural environment, which is associated with global problems caused by the deterioration of the environment and unprecedented measures in connection with the pandemic. Taking into account the fact that the introduction of elements of fine art into the architectural space is always accompanied by only positive emotions, the necessary design of various types of Art objects in the modern architectural space has been determined. It is indicated that the artistic material is the main factor in the objects of fine art, capable of participating in the formation of the aesthetic perception of the environment. The analysis of the existing sources of theoretical and practical experience has shown the relevance of this problem. Based on the results of the analysis, the main properties of the colored surface were systematized, identified and determined, which affect the perception of the texture of colored surfaces of different types of art forms of Art objects, depending on the following factors: 1) color saturation and lighting; 2) distance from observer; 3) property of the surface of the material and the nature of its processing; 4) the color tone of the material surface, its saturation and lightness. Methods of its use in different types of Art objects are proposed. Typical examples of the practical implementation of the use of Art objects using the possibilities of a colored surface in a modern architectural space, made by the authors of the study and modern examples of world art, are presented in a visual table. Based on the results of the study, the main tools were identified that may be necessary in the design practice of architects, designers, artists to create a harmonious architectural environment.
