There is no red in the illustration, just shades of blue and gray.
Another illusion. These two pictures are identical even though the roads look very different. pic.twitter.com/InFvxdMDsG

The claim is that the two pictures are identical. As far as I can tell, it’s true. Check the details, block by block. Then use straight edges to block out parts of each picture and compare a part of one picture with the same part of the other. You’ll have to conclude, the two pictures are identical, and they are oriented in exactly the same direction.
I believe this is one of the best optical illusions I’ve ever seen.
