If a person stares at a bright yellow object for an extended period, then looks at a white wall, which consequence follows due to retinal fatigue?

💡 Explanation

When staring at yellow, the cones sensitive to yellow light become fatigued. Consequently, when the person looks at a white wall (containing all colors), the fatigued yellow cones respond less, therefore the brain interprets the signal as an overrepresentation of the complementary color blue, rather than a desaturated color shift.
