Essay / Research Paper Abstract
A 6 page discussion of color. The author examines color and our perception of it from both a scientific and a cultural standpoint. A discussion is included on how the light spectrum relates to color and how techniques such as infrared photography can be used to more carefully explore color. Details on how color relates to our biological, chemical, and physical world as well as to own behavior is included. Information on how a chameleon changes color, how gemstones vary in color according to their chemical composition, and how color in our environment is currently believed to be capable of affecting our behavior and our performance. Bibliography lists 8 sources.

result of what is referred to as the emission spectrum. Any one atom can emit high to low energies and thus varying levels of emitted photons and frequencies of
light waves. When a photon meets an electron in a lower energy state it can be absorbed and thus transition to a higher energy state. This phenomenon is
referred to as the absorption spectrum, a phenomenon which is unique according to the particular element. The specifics of color can vary according to the situation. Consider, for
example, the infamous chameleon. This reptile serves as a perfect example of the manner in which color can be determined by biological factors. It is noted, in fact,
for its ability to change color before our eyes. The colors which a chameleon has in its palette are really just various shades of green, brown and gray.
The precise range, however, is species-dependent. When light reflects off their skin it is actually reflecting off a complex system of pigment containing cells. These cells contain both
red and yellow pigments called chromatophores and beneath the chromatophores are specialized cell layers which reflect blue and white light (Raxworthy, 2002). Underneath those cell layers is a layer
of brown melanin (Raxworthy, 2002). By opening and closing their melanophores, a term used for a specialized type of cell, the chameleon can control which pigments the light hits
and, in turn, which color of light is reflected back to the observer (Raxworthy, 2002). Raxworthy (2002) notes:
"Levels of external light and heat, and internal chemical reactions cause these cells to expand or contract. A calm chameleon, for example, may exhibit green, because the
