There are optical illusions where you stare at a highly saturated color for a while and then close your eyes, seeing a negative of the image you stared at in your eyes.
Continuous color sensing is just one of the fictions our brains tell us unfortunately. If you play outside without sunglasses you will find that everything inside looks extremely dark. That's not just pupil contraction, although that plays a role. The photo receptors in your eye have a recharge rate, and very loud colors can exceed that. Your brain keeps adjusting to compensate but you can catch it via rapid changes, like closing your eyes.
