Numerous factors affect the design of interior architecture of a space. One of the basic quality factors of a realized interior design is color. Complex nature of colors and their impact on the art, culture, psychology and religion has been often studied. Color is observed as a fundamental quality of our visual perception. There are numerous developed theories and assumptions related to the esthetic comfort offered by colors, and to their effect on human psyche.
