Color constancy
Perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object
Color constancy is the ability of the human brain to perceive the colors of objects as relatively constant in various lighting conditions. This means that the perceived color of an object remains the same regardless of changes in the color or intensity of the light falling on it.
In simpler terms, when we view an object in different lighting conditions, our brains automatically adjust to compensate for the changes and allow us to perceive the object as having the same color.
Color constancy is achieved by a combination of processes, including color adaptation, memory, and cognitive processes. Our brains use information from previous experiences and from the surrounding environment to determine the true color of an object, rather than simply relying on the light that is reflecting off its surface.
For example, a white sheet of paper will still appear white whether it is viewed under the bright sun, in the shade, or under a yellow-tinted light bulb, thanks to color constancy.
Color constancy is an important feature of human vision, as it allows us to perceive the true color of objects in various lighting conditions, helping us to navigate the world around us more accurately.
