As you can see, the girl is wearing a different lipstick in one of the shots.

Time for another quick visual test. Take a look at the image below and try to find the hidden number that is hiding somewhere in the colorful background.

To help you solve this puzzle, we have a pro tip ready for you. Don’t try to focus on the blocks of color too much. In fact, you should try doing the exact opposite.
