Understanding Color: Definitions And Dimensions

Write a short note on color.
Answer:

Color can be defined as a complex psychological phenomenon resulting from the behavior of light through its wavelength to the human eye.

Color is the effect of light waves striking the retina of the eye.
It is produced by the reflection, absorption, or transmission of light.
It is what is seen apart from size, shape, and texture.
An object by itself does not have color. It has only the ability to reflect or transmit light from the various parts of the spectrum and this reflected or transmitted light is seen as the color of an object.
Therefore, “no light, no color.”
They are always in the same order; violet which has the shortest wavelength is at one end of the spectrum and red which has the longest wavelength is at the opposite end. By recombining these waves, the color of the source is reproduced.
Metamerism is the change in color matching of two objects under different light sources.
Perception of the color of an object is entirely a subjective experience, a result of a physiological response to physical stimulus.
There are three dimensions of color, i.e. hue, value, and chroma.
- Hue describes the dominant color of an object.
- Value can be defined as the lightness or darkness of a color.
- The degree of saturation of the hue is known as chroma.
For measuring the color there are several methods, i.e. Munsell system, RGB system, etc. Munsell system is used commonly as the parameters of color are represented in three dimensions. This system measures color quantitatively.
