MIXORA CONCEPT

Color constancy

The tendency to perceive familiar surface colors as relatively stable despite changes in illumination.

colorthoughtbridgeStrong evidence
IN PLAIN LANGUAGE

The visual system uses surrounding information and assumptions about light to partially discount the illuminant. Constancy is useful but incomplete, so physical samples can still shift visibly across lights.

What “Strong evidence” means

The core definition or effect is well established across authoritative standards, foundational research or a broad research literature. The label does not make every practical prediction certain.

The tendency to perceive familiar surface colors as relatively stable despite changes in illumination.
EXAMPLE

White paper still looks roughly white in shade and warm indoor light even though the light reaching the eye changes.

COMMON CONFUSION

Constancy does not mean color appearance is perfectly unchanged.

ASK YOURSELF

What cues is the visual system using to infer the illumination?
