What color are they?

[Brian37]

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. What else you got?

Boru, does someone pay you to be a constant contrarian to every post I make?

It isn't one factor that can cause someone to see something differently as far as color, but multiple factors.

1. Light refracting off the object and the difference between what gets absorbed and what bounces back to your eye.

2. Angle. Light source, natural or man made.

3. Point of view. Just like an 18 wheeler that is two miles in front of you on a flat highway is going to look small compared to the one right next to you. The person in that 18 wheeler 2 miles in front of you is going to see you as small too until they approach you. 

4. Even imperfect eyes. If you have "color blindness", which is a horrible term, and does not mean one only sees in black and white, but if you have that malady, your eyes can see any given color slightly different than others. 

I cannot address the example given. I can say however it is no different seeing shapes in clouds. If you want to see something badly enough you will. The original post(the person who wrote the story in the link.  Link s simply another attention seeker just like that stupid dress bullshit.
