If you’re too lazy to do the Photoshop/Paint thing, or if you just want to convince yourself that it’s real “with your own eyes”, try cover the white triangles at the top of the picture with your hand or a book. That helps to see that the diamonds actually are all the same. At least it does for me.

Wow!!!

so many posts with the same answer. don’t you ppl read before you post??

Next time just cut and paste your post…it’s quicker

Msg from Abeo: It’s because the comments don’t show until they are approved, so people don’t know if it’s already been answered at that point

“Erm how does this work? I just copied a screenshot of the illusion into paint and then selected and copied just the diamonds (with no other colours) into another paint but they still look like diamonds…. shouldn’t I now see a just a solid block of colour?”

No. All the diamonds have the same GRADIENT of colour on them: light at the top and dark at the bottom, so they contrast at the edges where they meet.

If you think about it, no amount of white at the top of an image is going to make you see diamonds in a solid block of colour

@Steve: No the trick is not the other colours. The trick is that the diamonds are not uniformly coloured but have a gradient.

Fantastic… one of the best illusions I’ve seen!

A very nice optical illusion.

I was inspired to reproduce this at once. Very easy to do with any graphic software (I use GIMP). Printed it out, it works perfectly, and it confused my wife thoroughly

As a web designer, I see this happen all the time with gradients and what-not!

Hey guys,

I think Beau Lotto talks about this effect on TED.com. Check it out for a clear explanation into this illusion.
Search- “Beau Lotto: Optical illusions show how we see” in the TED search field.

Enjoy
