What color are they?

Then why do the shoes appear black to some people and white to others?

I just told you. Light refraction, and even slightly moving your computer screen too, can make the color seem to change. Ever see those black and white puzzle patterns in a social media post? Angle and refraction can give the illusion of color change. Just like that fire waterfall I told you about in the prior post. 

You've heard that old saying "Red sky at night, sailor's delight, red sky in the morning, sailors take warning." But if you are hundreds of miles up in space at the space station, from your point of view you are only going to see the blue of the ocean, the white of the clouds and the brown of the earth.

I just tried looking at the image again. I moved about to look at it from different angles, and the shoe still looks black. In order for your explanation to be correct, ALL of the people who saw it as black would have to be viewing from a precisely identical angle, ditto for everyone who sees it as white.  This is unlikely to the point of imbecility.

What else you got?
