Here's your latest Internet optical illusion . . .
There's a picture going around that's a black and white photo with a light grid of different colored squares on top of it.
And even though the lines of the grid aren't very big, our eyes color in the areas in between them. So it makes the entire photo look like it's in color, especially if you move a few feet away from it.
The optical illusion works because our brains are constantly trying to predict what things are SUPPOSED to look like . . . so in this case, it's filling in colors because it thinks that's right.
