Whiteness Constancy, Adaptation,
and Surroundings
The brain wants to perceive white surfaces (those
with a white reflectance spectrum) as white. A sheet
of white paper under fluorescent or incandescent
lights looks white, even though neither of these
lights is white. White on a monitor in a dark room
looks white, even though the white on two different
monitors may look very different if you see them
side by side.
When viewing a monitor in a lit room, you have
adapted to the illumination of the room, not to the
illumination of the model. Even if a model is
computed and displayed correctly, it may still be
seen as if you are looking into the room from the
outside—or, more likely, as if the color of the model
is wrong.
