Being a non Biologist, I searched the internet of what we might see in the 2. image-animation (Also see link, April 6, 2026 under). It is called Negative afterimage. They are temporary visual sensations where one can see an image in inverted colors or brightness. They occur when retinal photoreceptors (rods and cones) become overstimulated and fatigued, causing them to loose sensitivity for a short time.
