Are the two balls of the same color?

June 12th, 2019

Look at the two balls below. What colors are they?

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?

Same color?

The two balls are of the same color!

This is a good example to show that:

  1. Our brain (and us) is easily tricked
  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.

Try Stork, a research tool we developed

Stork is a publication alert app developed by us at Stanford. As a researcher we often forget to follow up important publications - and it's practically impossible to search many keywords or researchers' names everyday. Stork can help us to search everyday and notifies us when there are new publications/grants. How Stork helped me?
