In this research, the effects of different colors (cream, blue and green) used in interior space of school corridors on perceptual performances of students were tried to be determined. For this purpose, the corridors of İncirli Technical and Industry Vocational High School in Ankara was selected as the research environment. Students were requested to evaluate the corridors with three different colors by means of using semantic differentiation scale consisting of 11 adjective pairs. Gained data were statistically evaluated and important results were reached. As a result of this study it was determined that cream colored space is perceived more positively in corridors used different colors compared to blue and green colored space. Also it is seen that beginner students have more positive approaches in their space perceptions compared to students studying in upper classes. According to the data obtained, it is considered that education building will have contributions to strengthen the spatial image perceived by students and may be used to increase the satisfaction of students about their schools.
