Effects of colored lighting on the perception of interior spaces
(2009) Odabaşıoğlu, Seden
The aim of this study is to understand the effects of colored lighting on the perception of interior spaces and to compare different colored lightings in order to understand their effects on interior space perception. The experiment was conducted with the same sample group for three different lightings which are red, green and white. The participants were ninety-seven students from different departments of Bilkent University, most of them from the Department of Interior Architecture and Environmental Design. The study was conducted in three phases. Firstly, participants were tested for color vision deficiencies and the ones who passed this test entered the first part of the experiment. They evaluated the experiment room under red lighting in the first phase. Secondly, they evaluated the experiment room under green lighting. Lastly, they evaluated the experiment room under white lighting. It was found that colored lighting (red and green) affects the perception of an interior space and the space perception differs according to the color of the lighting for some of the evaluative factors.

The effects of correlated color temperature on wayfinding : a study in a virtual airport environment
(2013) Kumoğlu, Özge
The aim of the study is to understand the effects of correlated color temperature on wayfinding performance in airports and to compare different color temperatures in order to understand their effects on wayfinding performance. The experiment was conducted with three different sample groups in three different lighting settings that are 3000 K, 6500 K and 12000 K. The participants were total ninety graduate students from twenty-one different departments of twenty-six different universities. The study was conducted in a single phase. The volunteered participants experienced the desktop VE one by one. The participants were seated at the computer and were tested by the researcher. They were asked to direct the researcher from the starting point to the final destination which was stated as gate numbered 109. It was found that correlated color temperature has no significant effect on wayfinding performance in terms of the time spent, the total number of error, the total number of decision points and the route choice during finding the route. However, the correlated color temperature has a significant effect on experiencing hesitations. It was found that the total number of hesitations decrease while the correlated color temperature increases from 3000 K to 12000 K.
