Relatedly, I didn't "get" Rothko's paintings until I saw one in real life last year. Easy to look at through a screen and not get the effect that it has, what with everything on the screen being so pixel perfect. For me, looking at those Rothko's in real life had me thinking there was a pattern in the color somewhere just out of reach for me, that if I looked closer I could see a pixel or catch a line somewhere that would tell me what was really driving all the colors. It drew me in in person in a way that it simply could not via the screen or some sort of other reproduction. What he did with colors is magical and the stories around others calling it easy or trivial to do and then failing hard themselves are also fun to consider afterwards.

Vasarely was the master of this. Absolutely insane technical skill required to calculate and sketch the geometry, and mix and paint shades so precisely.

And it never even crosses your mind, because you're too busy looking at the image.

It's deeper than cognition.

You have special nerves that link multiple receptors in your eyes, specifically to recognize lines. There are more in the vertical than horizontal, so you can more readily see vertical lines ("Watch out for that tree!").

Repetition is deeply integral to our visual experience.
