After writing the article on colour illusions yesterday I was dissatisfied with the poor quality of the images in the Scientific American slideshow. Additionally, some of illusions were so amazing that they were hard to believe at all, and having poorly defined images just confused the issue. So I decided to make some of my own.
I used PowerPoint, which has the advantage that if you download the PowerPoint file you will be able to de-construct the images, and play around and convince yourself that your colour perception really is playing tricks with you! Enjoy 🙂
