Architecture as an art of space must open up to creative activities and contemporary humanistic knowledge, so as not to be reduced to the engineering and technical field, to be for people and respond to contemporary cultural challenges. The significant reduction in the number of hours of art classes in architectural study programs, which has been progressing for a decade, results in the loss of creativity among students and prompts them to imitate the existing aesthetic and formal solutions in design. One of the fields of interdisciplinary activities in architecture will be deepening the awareness of the essence of the correlation of painting and architecture, where the wall is the common value and field of activity. Color, and wall painting in particular, has enormous potential in creating spatial impressions, in transforming and complementing them. Promoting knowledge about the dependencies of color and space, as well as the practice related to the design and implementation of painting in architecture are important factors in the development of creativity in teaching architects.
