I spent so long trying to make myself see blue-and-black. Kind of resigned that I can't do it.

I've managed to game other optical illusions by covering bits of them up, to break the effect, and then slowly shift the amount covered. Cover one eye. Focus on one part of the image.

I can make the Necker cube be in either orientation.

I've seen The Spinning Dancer run in both directions.

But The Dress remains determinedly white-and-gold.

On the other hand, I've never seen white and gold.

These guys apparently reproduced the effect.

One apparently either sees white socks and pink crocs, or green socks and gray crocs.

If it is true that the differential interpretation of the light source causes the disagreement about the percept, we should be able to recreate the effect de-novo:

And we did: We put a pink croc under green light so it looks grey, then added white socks which — reflecting the green light appeared green. People who know that these socks are white used the green tint as a cue that something is off with the light and mentally color-corrected the image. To them, the croc looked pink, even though the pixels are objectively grey. People who took the color of the socks — green — at face value, saw the croc — consistent with its pixel values – as grey.

EDIT: For me, it's green socks and gray crocs.

I see green socks and pink crocs lol

But I think it's because I'm color correcting the Crocs from the green, but the socks, while I acknowledge are likely white in reality, do look very green from reflecting green light

But then, yeah, there's the difference of "do we take it at face value, or try to figure out what the 'real' colour is in neutral light?"
