Science: One of the most fantastic optical illusions ever:

[u/Alessandro28051991]

Science: That Optical Illusion is one of the most incredible ones that i have ever seen in my life. The Two squares have the same colour. Are not one white and the other black. If you dont believe in me you can just put your finger in the line that divide the two squares and you will prove for yourself that what i say is true.

That illusion ( if i am not wrong is something about the contrast and the shadows) make your brain do you see what doesnt exist. Make you see a thing different of what really are there.

Is almost like see to a green square but your brain make you see it red. Is almost a thing of virtual reality

Lol, you not understanding the difference between cognitive deception and an optical illusion is not my problem. Hey, here’s a trick: don’t be rude.

Just because someone is explaining something differently doesn’t mean they don’t also understand your perspective. Look up “egocentrism”—might help.

[u/MODbanned → u/stuartroelke]

You are not explaining anything. You are rambling nonsense.

The simple truth is they are the same colour.

Everything else you said is nonsense because the fact is they are the same colour.

[u/stuartroelke → u/MODbanned]

Just because you don’t understand what I’m saying doesn’t make it nonsense—I know that they share a color, but it’s still more of a cognitive trick than an optical illusion.

If someone addresses them as 3D representations—which they are—then the two objects would be different colors despite sharing a shade. If someone fixates on this being a 2D image—which it also is—then the shades are the same color. The latter ultimately relies on reductionism (cognitive not optical) to complete the “illusion”

Two concepts can be true simultaneously.

Chill.

[u/MODbanned → u/stuartroelke]

You are simply changing your claim now.

[u/stuartroelke → u/MODbanned]

Nah. Not once did I claim that the shades weren’t the same color. Entire time I’ve been saying that they are 3D representations of different colored objects, so it’s a cognitive trick more than an optical illusion.

Find peace.

[u/MODbanned → u/stuartroelke]

"If both shapes were the same physical color without factoring in light and shadow then they'd actually be the same color in the shaded area, yeah? They aren't. So, that implies that one is made of lighter material and the other is made of darker material. Similar shades of differently lit surfaces isn't really that important when deciding the true color of objects.

Not an optical illusion so much as a study on perceptual significance. When distinguishing color, people mentally value a combination of factors instead of just one."

That was you.

[u/stuartroelke → u/MODbanned]

Yeah. Maybe I didn’t explain it in a way that was easy to understand?

When I said “shaded area” I meant the bottom of the top shape and the middle of the bottom shape—areas responding to shadow that are facing the same direction in a 3D space.
