It's really interesting how quickly and easily our brain and image perception can be tricked into perceiving images and objects as different or similar, even though they might not be so. It reminds me of the grey box optical illusion: https://www.jagranjosh.com/general-knowledge/optical-illusion-grey-squares-1649739440-1

Agreed, one thing that was interesting to me was how the juxtaposition of these differently contrasting grey and white boxes can be used to simulate "movement" in an image (thinking back to optical illusions where an object is seen to move counterclockwise or whether a horse is galloping). It's quite interesting to me how graphic designers can place these grayscale boxes with different levels of contrast next to each other to trick the human brain into seeing movement when staring at a static frame.

It's intersting that color is more a matter of perception than a physical quality. Humans perceive colors differently depending on the context—for instance, a higher contrast can make a white box appear whiter. This variability in perception might be rooted in our evolutionary history, where the absolute color of an object was less important than its relative appearance in different environments. Recognizing contrasts and changes in color could have been crucial for survival, aiding in the identification of threats, resources, or changes in the surroundings.

I agree with maxwelljin, it is interesting how humans perceive colors. I imagine that being sensitive to color contrast would be crucial when identifying a threat or food, especially in foresty areas.
