Color planning by fuzzy set theory

The authors propose a system to plan a color arrangement in interior space such as rooms and offices. The system is based on three main processes: a determination process of dominant colors, a determination process of harmony colors, and an adjustment process of the resultant colors. In the first process, the dominant color of the interior space is determined from the linguistic representation of the users image for this space by fuzzy set theory. In the second process, the harmony colors for the dominant color are calculated by P. Moon and D. E. Spencer-Spencer´s harmony theory, taking into account the area effect and linguistic inputs. If users cannot satisfy the resultant colors represented on a CRT display, the system can adjust the resultant colors to the user´s favorite color by linguistic representation in the final process
