Color
- "The
selective reflection of light waves in the visible spectrum. Materials
that show specific absorption of light will appear the color of
the wavelength that they reflect." - MPI Glossary of Terms.
A practical knowledge of color is important in the various avocations
of life. The possession of a keen sense of color increases intellectual
and even the literary capacities of an individual. Color has a definite
effect on emotions, and influences to a marked degree the health
of an individual. Almost everything that man consumes, wears or
enjoys is brought to his attention through the medium of color.
Color communication between all types and fields of industry should
be smooth and understandable.
 The
simplest way to study anything is to find its elements, essentials,
or first principles. We will attempt to break it down into the easiest
terms possible, so it will be easier to comprehend. There are three
essential elements that enter into the phenomenon called color.
These are:
- light - the illuminant,
rays of visible radiant energy (sun, electric light, fire, etc.)
- the object - the modifier of the light, the
ability to absorb and reflect portions of the light.
- the eye - the receiver or observer that
focuses on the reflected light and, along with the brain, interprets
the colors seen.
