This paper examines designing a research on architectural coloring process and approaches to develop a color-emotion space model for human visual system. Matched on relevant methodology, a study is explored to compare modes of color evaluation with the following hypothesis; can slides of a real setting be used instead of 1/1 model study for space perception? The study is composed of two interrelated parts. Firstly, 1/1 model room is designed in order to investigate lighting quality, color evaluation and visual perception in respect to the lighting scheme. Secondly, slides of this model room are projected to a participant group to evaluate the room for lighting quality, color evaluation and visual perception. The methodology is based on investigating between the two cases. The 1/1 scaled model and replication of the same study by its slides are analyzed from lighting quality and lighting quantity point of views. The findings suggested that there are similarities between the results, however the 1/1 model room provides a controlled setting for human based research, visual impact is stronger and subjective impression is more realistic. As a visual research method, replication of a real setting (by its slides) can be used instead of constructing the real case which may also bring flexibility and lower cost to design studies.
