Color is an essential factor for perceiving objects and their interaction. There are many alternatives to color selection in interior design. Colors can be selected according to a user, physical characteristics of the space or a concept. In this context, research has been conducted on the interior color scheme preferences and emotional states with university students. It contains the findings obtained during an interior design exhibition, which was organized at the interior design department of the university. This exhibition was organized for sampling interior color information, selection methods, and using forms. For the exhibition, to be able to observe the changes in the perception of space and the effects of the color, the visuals were arranged according to different color selection methods in the same space. A survey was conducted during the exhibition to examine color scheme preferences and the relation with emotional states of students on interior designs. In the survey, students were asked whether they would prefer or not each interior space and which emotional state is expressed for each visual separately. The statistical analysis was made, and according to the answers given in the survey, comparative results appeared. It is concluded that the students who participate in the survey have meaningful relationships on the spatial color preferences, and differences are determined in emotional states.
