OBSERVATION

An object's apparent color can vary with illumination.

MODEL

Reflected light stimulates cone receptors. Their overlapping responses are combined by the visual system to support color perception. [41]

EXAMINATION

The same object can be compared under different lighting while viewing conditions are recorded. Observation and explanation should be kept distinct.
