Excellent Optical Illusion

Here’s another excellent optical illusion. It’s a variation on one we’ve already seen here. Despite what your eyes tell you.the circles are all the same color, and it’s pretty easy to prove it. I leave that as an exercise for the reader.

You can easily see there are two colors of lines: purple and green. Only half of them pass through each circle, and that’s what makes the difference. The purple lines pass through five of them, making them look pink by contrast. The green lines pass through the other six and make them appear lemon yellow.

This tells us you have analog eyes that see colors relative to each other by contrasting and comparing. Digital electronic “eyes” like a computer uses see color as it really is, regardless of other colors in the vicinity.
