About This Design

Bezold Effect (Optical Illusion)

Bezold Effect (Optical Illusion)

When you take a look at the picture are some of the red lines darker than others? Showcase the Bezhold effect with any of these optical illusion gifts. Explanation caption says the following: "Notice that the red seems lighter when combined with white & that the red appears darker when combined with black. This optical illusion is named after Wilhelm von Bezhold (1837 - 1907), who discovered that a colour may appear different depending upon its relation to adjacent colours." Educational visual fun psyche / psychology attitude for those who understand that colour is relative!

Creator Review
Looked great and was perfect for my Nana's 99th it arrived super quick so much quicker than sending the original from the other side of the world! My Nan loved my artwork too and the picture of us inside helped her remember who I was as she has Alzheimer's. Crisp and clear. Bright and colorful true to the original artwork I created. The photo we placed inside also looked great and clear.

This was used as a Mother's Day card and my mother absolutely loved it! The artwork and attention to detail is stunning. It's as if the hare could jump right out of the card at any moment. The print quality and colours are of a very high standard and show the beautiful hare in commendable detail.
