This reminds me a bit of a Tv programme I saw years ago about an american named Land (he invented the Polaroid camera) and his experiments with colour - I remember one wher he was showing how colour is affected by surrounding colours, and having masked out squares in a projected colour grid, showed how you could predict what the missing colour would be based on the surrounding colours.

Illusion 1 is impressive; illusion 2 less so. But illusion 3 is a bit of a fraud, I'm afraid. I've compared a highly blown-up version of the centre pieces of both objects, and they are in fact different colours. The right hand piece has more yellow components on a pixel-by-pixel comparison.

Nevertheless, with the mask on they look the same.

I thought the one on the right looked yellower even with the mask on...

But this does intriguingly link into our discussions about colour. It is extremely irksome that this seems to support your view. Tongue

Having looked again at illusion 3, I must definitely call into question the existence of "yellow" and ergo "red". Bah.

1ST one was freaky.

2ND one was easy to see.

3RD one I'm with Blink...I thought the right one was lighter even with the mask on. :sad:

Enough of the smugness already. Allow me the dignity of conceding grumpily.
