Quizplus · Accepted Answer

This scenario illustrates colour constancy, which is our brain's ability to perceive the actual colour of an object despite changes in lighting conditions. Even though the bluish light should make the apple appear more blue, Stewart continues to perceive it as red, indicating that his brain is adjusting for the lighting and maintaining a stable colour perception. This phenomenon is part of the broader topic of perceptual constancy, which refers to our ability to maintain a stable perception of objects despite variations in their sensory input.
