Beau Lotto: Optical illusions show how we see them

I love TED talks. I stumbled across this one on Derren Brown’s blog (I follow him on Twitter…). I remember during the early 00’s I would always visit optical illusion websites out of curiosity. The days of dial-up and static .gif images.

There is a part in this video where Lotto asks you to stare at a green box and a red box (looks orange to me), and then look at 2 symmetrical but identical images below. He describes the colours above should appear on the identical images, making them look, well, un-identical. However when I look at them, the colours swap over. Underneath the green box the image looks red and vice versa. Is this what’s supposed to happen? I’ve repeated this 3 times now and each time the pictures go opposite colours. Quite strange.

I’ve always known I’m stronger in my left eye even though I am right-handed. I’ve discovered this through using viewfinders on cameras and, strangely, archery at summer camp in Year 6. Not sure why but I always remember that. I don’t think this has anything to do with the green and red thing though.
