Color in interior spaces
(1992) Demirörs, Müge Bozbeyli
Color can be approached from different perspectives and disciplines such as, biology, theory, technology, and psychology. This thesis discusses color, from the stand point of interior spaces, which to some extent involves most of these disciplines. The aim of this study is to review the research on environmental color. It will summarize what is empirically known about our responses to color, how, if at all, color ) influences the perception of an interior, how it is effected under different light sources or if it is effected from each other. The effects of light on color will try to be verified by using a 'color and light simulator'.

Effects of color and colored light on depth perception
(2010) Atlı, Deniz
The main purpose of this study is to understand the relationship between different objects and background colors, and depth perception in interior spaces. The experiment was conducted in two phases which consist of colored background light pairs (cool white-orange, cool white-blue, cool white-green, cool white-red, warm white-cool white, red-green and orange-blue) with colored objects (orange, blue and gray) in front of them. A forced choice paired comparison method was used to evaluate the differences in depth perception caused by colors. The participants were students who were having their internships in Philips Research Eindhoven, Netherlands. Firstly, participants were tested for color blindness and visual acuity, and the ones who passed these tests participated in the experiment. After the first phase of the experiment, a second part was required in order to obtain more accurate results. The participants who had internally consistent results in the first phase participated in the second phase of the experiment. In both phases, participants judged the distances of two same colored objects in front of colored lit background by choosing the one which they perceived as closer to themselves. As a result, differences between hues are smaller than the variations in perception of the participants, so hue has a really small effect on depth perception when evaluated monocularly.

The impulsive effects created by the use of color on food and beverage packages: their relations with the symbolic meanings of foods and beverages
(1994) Tonak, İrem Petek
The intention of this study is to aiialyze the role of symbolic meanings and physical attributes of foods and beverages reflected by the use of color on their packages in the creation process of impulsive effects.

Structural coloring in large scale core-shell nanowires
(American Chemical Society, 2011) Khudiyev, T.; Ozgur E.; Yaman, M.; Bayındır, Mehmet
We demonstrated two complementary size-dependent structural coloring mechanisms, interference and scattering, in indefinitely long core-shell nanowire arrays. The unusual nanostructures are comprised of an amorphous semiconducting core and a polymer shell layer with disparate refractive indices but with similar thermomechanical properties. Core-shell nanowires are mass produced from a macroscopic semiconductor rod by using a new top-to-bottom fabrication approach based on thermal size reduction. Nanostructures with diameters from 30 to 200 nm result in coloration that spans the whole visible spectrum via resonant Mie scattering. Nanoshell coloration based on thin film interference is proposed as a structural coloration mechanism which becomes dominant for nanowires having 700-1200 nm diameter. Controlled color generation in any part of visible and infrared spectral regions can be achieved by the simple scaling down procedure. Spectral color generation in mass-produced uniform core-shell nanowire arrays paves the way for applications such as spectral authentication at nanoscale, light-scattering ingredients in paints and cosmetics, large-area devices, and infrared shielding. © 2011 American Chemical Society.
