Look at the two balls below. What colors are they?
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:
The two balls are of the same color!
This is a good example to show that:
- Our brain (and us) is easily tricked
- Color is a construct of our brain. Put it in a different way: we color the world we see!
- The so called “reality” does not exist.
