What it is
Color constancy is why a white sheet of paper can still look white in warm indoor light or cool daylight. The visual system interprets color in context rather than reading raw wavelengths directly.
Basics
- Perceived color depends on surrounding colors and illumination.
- Color constancy is useful but imperfect; it can create illusions and disagreements.
- It matters for photography, product color, interiors, and visual design.
Notes for later expansion
- Later expansion should connect to shadows, white balance, and color illusions.
