Color Constancy: Why Does Sasha's White Shirt Still Appear White Under Different Lighting Conditions?

Why does Sasha's white shirt appear white under different lighting conditions?

Sasha's white shirt appearing white under different lighting conditions is due to a phenomenon called color constancy.

Color constancy is a fascinating aspect of human visual perception that allows us to perceive the color of objects as relatively constant under varying lighting conditions. In the case of Sasha's white shirt, color constancy plays a significant role in ensuring that the shirt appears white regardless of the type of light illuminating it.

When Sasha observes her white shirt in bright light or under a green-colored light bulb, her brain adjusts the color perception to maintain the perception of whiteness. This adjustment is essential for our ability to accurately perceive the colors of objects in different environments.

The concept of color constancy highlights the complex mechanisms at play in our visual system, allowing us to make sense of the world around us despite changes in illumination. It showcases the remarkable capabilities of our brains to interpret and perceive colors consistently, even in challenging lighting conditions.
