Introduction
The color we perceive when
we view an object is influenced by several factors. These include the
characteristics of the light source under which it is viewed, the way
the object absorbs, transmits, or reflects the light waves striking
it, the physical condition of the viewer's eyes, and the psychology
of the observer. Color is not a property that is a physical part of
the things we see, it is simply the effect of light waves as they bounce
off or pass through the object being viewed. If it were not for light,
the objects around us would have no color.
This course begins with a brief description of light and how light behaves to produce color, and is followed by a discussion of the psychological, physiological, environmental, and circumstantial factors which influence color perception. It then goes on to cover some of the theories of color vision, and concludes with a survey of the color vision abnormalities.
Upon completion of this course the student should be able to:
-
Explain how light behaves to produce color
- Describe the physiological, psychological, environmental, and circumstantial factors that affect color perception
- Describe at least four of the theories of color vision
- Explain our current understanding of color vision perception
- Describe four categories of color vision deficiencies
- Explain the subcategories of anomalous trichromasy and dichromasy
