What is Color Constantie?

Color Constanting is part of a system of visual perception that allows people to perceive color in different conditions and see a certain consistency in color. Apple, which is red in a bright morning sunlight, also appears red under the candle and in the late afternoon, when the wavelengths of the available light are actually very different. Similarly, if the apple is partly in the sun and partly in the shade, the observer reads the whole apple as red. This allows someone to recognize the apple, even if the conditions have changed, with the eyes perceiving color as relatively constant.

This system is part of a larger system of subjective stability. Subjective stability uses the brain to help people perceive objects in changing situations. This ensures that they can recognize those objects that help with the understanding of the world and can also be important for safety. For example, the ability to recognize a particular shape can help help and may also be important to compensate the distance atviewing of the scene. Subjective stability also allows people to identify and interconnect thematic elements, as can be seen when people recognize a work of art because it depicts a well -known scene.

Color Conndance uses input from different conical cells in the retina. The cones are sensitized to different wavelengths of light and their collective data are processed by the brain to determine which colors someone looks at. Colors can be influenced by the wavelengths of light and the surrounding colors, so the color can look very different depending on what is located next to it.

This aspect of the human color perception system was revealed in the 70s. In fact, it was a photographer who identified the phenomenon of color stability, perhaps because photos often require a very high Awareness of Color and available light. Color Constantie has been studying extensively since then to learn moreE About how people see color and how color distortion can be.

Many examples used to demonstrate color stability and tricks that can be played with color to use a grid known as Mondrian. The grid consists of a series of squares, while the experimenter manipulates the available level of light to see people perceive the colors of squares. For example, an orange square may appear red in a different wavelength, and squares of the same color may seem different, depending on which colors surround them.
