Optical Illusion
So I know this will be hard for you to believe, but the two squares marked "A" and "B" below are exactly the same shade of gray.
This illusion occurs because our brain does not directly perceive the true colors and brightness of objects in the world, but instead compares the color and brightness of a given item with others in its vicinity.
Here's some more.

It's true! I put a piece of paper up to the screen in between A & B and I could see it... wild.
Not true. Something happens between England and Seattle to make that not true even if I squint and use paper.
How hard did you squint?
:) Try printing out the photo, cutting out the squares and setting them next to each other. They're the same shade, Lucie, even in the UK.
Are you sure? I put my finger between the A and B squares for a good two minutes and told myself they were the same hue. But the one still seems lighter.
I was wrong. If you increase the picture size then it actually is the same. . .bizaar

hm.... must be me. l made it bigger and stared for 2-mins. no joy. B is lighter.
That's what optical illusions do. They optically look one way, when they're really another way. Don't keep staring at it to see if you can prove it, you have to prove it objectively = print out the picture, cut out the squares and put them next to each other.
