Are the two balls of the same color?

Blue and Green balls?
Blue and Green balls?

To me, the left ball is definitely blue, and the right one is green.

If you see the same way, Haha, you (your brain) is tricked! I used photoshop to remove the background purple and yellow colors, then here is the result:

Same color?

The two balls are of the same color!

This is a good example to show that:

  2. Color is a construct of our brain. Put it in a different way: we color the world we see!
  3. The so called “reality” does not exist.
