Ooh yay thanks @debbie for the upvote.

@po Thanks for such a cool illusion! I never expected that A and B are the same. It’s amazing how our brain can trick us that much.

@po yeah, it's a cool illusion, but how do you tell whether the shade of grey is different or not? Is it just a coincidence and you can use some kind of computer program that breaks the color down to a mix of yellow, blue, and red so you can check if it's the same? Or can you calculate the shadiness of B using the intensity of the light and the density and thickness of the cylinder and then make A the same?
Just wanted to know....curiousity...unstoppable...

There's actually a video might be embedded within one of these posts if you put it into a color analyzer they're the same

[divinedolphin]

If you screenshot square A and square B separately, and copy-paste it into like google docs, you can see that they are actually the same.

@The-Blade-Dancer @divinedolphin Oh wow, I'll try both ways!

[The Blade Dancer]

Apparently no embedded video but google search works just as well
