COLOUR CONSTANCY Meaning and
Definition
-
Colour constancy is a perceptual phenomenon in which an object's color remains relatively constant despite changes in lighting conditions. It is the ability of the human visual system to accurately perceive and interpret the color of a given object, regardless of the variations in illumination.
When we look at an object, our brain analyzes the light that is reflected off its surface to determine its color. However, the lighting conditions under which we view an object can vary greatly, with differences in intensity, direction, and color temperature. Despite these variations, our perception of an object's color tends to remain stable.
Colour constancy is achieved through a complex process that involves the comparison of the spectral composition of the light falling on an object with the spectral sensitivities of the photoreceptors in our eyes. This allows us to discount the changes in the illuminant and perceive the object's color as unchanged. Our visual system has adapted to provide us with a consistent perception of color despite the inherent variability in the lighting conditions we encounter.
The phenomenon of color constancy plays a crucial role in our everyday lives, allowing us to recognize and identify objects under different lighting conditions. It also contributes to our ability to distinguish and categorize objects based on their color. This perceptual ability is not only limited to humans; some animals also exhibit color constancy, although to different extents.

Etymology of COLOUR CONSTANCY
The word "colour constancy" originated from the combination of the terms "colour" and "constancy".
- "Colour" is derived from the Old French word "color", which ultimately traces back to the Latin word "color".
- "Constancy" comes from the Latin word "constantia", which means steadfastness or consistency.
When these two terms are combined, "colour constancy" refers to the ability of the human visual system to perceive the consistent color of objects despite changes in lighting conditions or context.
