Color vision deficient people have a tendency to better night vision and, in some situations, they can perceive variations in luminosity that color-sighted people could not. It might also be worth mentioning how U.S. Army discovered that color blind people could spot “camouflage” colors that fooled those with normal color vision!

Regular Color Blindness Test no.1

Now let’s see if you are able to find a circle, star, and/or square in this Demonstration Card below. In reality, everyone should be able to see a circle, star, and square as this is a demonstration piece only.

Regular Color Blindness Test no.2

Let’s see how the previous, “normal” tests worked like. Try and find a circle, star, and/or square in 3 seconds or less in this picture below. While the colorblind individuals should only see the yellow square. Color normal individuals should see the yellow square and a “faint” brown circle.

Regular Color Blindness Test no.3

The question is same -are you able to find a circle, star, and/or square in 3 seconds or less in this picture below? Just the opposite from previous test, colorblind individuals should now see the yellow circle, while color normal individuals should see the yellow circle and a “faint” brown square.

Youtuber who goes under the name of brusspup noticed how this illusion has been around for a long time but always in the form of an image. His goal was to take it away from a flat piece of paper and turn it into a real, life-sized illusion that people could interact with. Obviously, brusspup has succeeded. He even included a scaled-down template for us to download and play with (file courtesy – brusspup).

Here’s how the author explained the effect and what he has done to achieve it:

The illusion works because of the “shadow” that falls on the checkerboard. Lets think of the square that the shadow falls on. Now picture that the shadow doesn’t exist: you would see a light colored square surrounded by the dark colored squares. But when the shadow falls on top of that light colored square, the shadow causes the shade to become darker but it also causes the surrounding darker squares to become darker. So within the shadow region the brightness and darkness of the squares are still relative to one another. But they are no longer relative to the squares that lie outside of the shadow.

So if you were able to pick up the middle square and move it to one of the outside dark squares, they would be 2 different shades, But the trick is ..that when you move the square you are moving it WITH the shadow still printed on the square. So now you’ve moved it out of its relative area, outside of the shadow region (but with the shadow still printed on the square) ..to the area where it’s the same shade as the “dark” square.

If you’re into scary illusions, there was this one particular picture that resembled today’s photo. I think the article went live almost 5 years ago under “Scary Illusion no.5” headline. Be sure to check it out and decide which one you like better. What I do know is that the real answer (for both of these pictures) is trickier than you think!

Sorry for such a long intro, just wanted to inform you I’m back now (and how last few posts were set to automatically appear each day, and were written few days ago ;). It’s also why it took so much time to get your comments approved. Now that I have charged my batteries once again, let me roll up my sleeves and continue sharing some good stuff! For today I bring you two posters that feature Missing Pieces illusion we featured some time ago. Seems that Chupa-Chups company jumped the optical illusion billboard wagon as well!

Solution – It’s strange enough how great majority of people firmly believe that both fingers point at the middle of the shape’s height, this also goes for the individuals aware that one on the right appears to be lower (?!). The truth is that only finger B points to middle of the shape’s height, which you can see demonstrated in the figure below:

The video you see below was produced by Leo Burnett’s advertising agency in São Paulo, Brazil and was done for Samsung to advertise their printers. Seems that agencies started using illusions much more frequently in their approach lately! Does it mean we can expect much more professionally produced optical illusion content in the future? Let’s just wait and see!
