Learn vocabulary, terms, and more with flashcards, games, and other study tools. The phenomenon of color constancy best demonstrates that an object's perceived color is influenced by its surrounding objects. Psychology System 4 Flashcards Metamerism, the perceiving of shades within two separate scenes, can aid to inform research study regarding shade constancy. Perceptual constancy psychology Color constancy is the relative constancy of the color of an object, despite the change in the spectral composition of the light falling on it. Color Constancy is an ideal reference for practising engineers, computer scientists and researchers working in the area of digital color image processing. Perceptual constancy, the tendency of animals and humans to see familiar objects as having standard shape, size, color, or location regardless of changes in the angle of perspective, distance, or lighting. Visual constancy is our ability to perceive that an object remains the same, even when the object projects different images onto our retinas in our eyes. Colour constancy is the tendency of objects to appear the same colour even under changing illumination. the tendency for, even after the observer has moved position relative to the object, the object seems to be in the exact same position and stance. d.
