Learning Event 1:
DESCRIBE COLORIMETRY
1. General. To learn the color TV system you must have a basic background in the
fundamentals of color.
The entire concept of color television is based upon how
the eyes react to light frequencies. From studies conducted on how people see, it
was determined that the color signals would occupy a certain amount of space in the
The process of specifying and
determining colors had to be accomplished before the color television system could
be developed. This is a science in itself and is known as colorimetry.
2. Colorimetry. The science and practice of determining and specifying colors is
referred to as colorimetry. The science of colorimetry was especially important to
the color engineers who contributed to the design of the present color television
system. Since the system had to be designed to reproduce things as they are seen
in nature, the characteristics of light, vision, and color were taken into
consideration.
a. Colorimetry is a very complex subject. It is not necessary to be an expert
colorimetrist in order to understand the takeup of the color picture signal and the
way in which it is used in the color receiver. However, a better understanding of
