This is one of the best illusions of color I've seen. The green and blue spirals are the same color! I had to use Photoshop to confirm it to believe it. Is our perception of color really that untrustworthy? Wow.From here and originally here.
Here's a similar one, perhaps even more remarkable. The hearts are all the same color. (As usual, click on it for full version.)

Yes, you better believe it.
It's all in the brain. Our retina registers elementary wavelengths, but our visual PERCEPTION, happening in the cortex, is based in great part on contrasts.
So is our moral perception...
The eye is so easily fooled. Look into how color movies work...Technicolor was based on a simple process (though difficult to come up with, as the simplest ideas usually are). The eye kind of fills in the blanks. Or I guess the brain when interpreting the signals. Makes you wonder why some people take their visions of UFOs, angels, etc. as proof.
Wow. Thanks for sharing, looks good.
I keep checking the hearts and they don't match. Did I misunderstand something? The "blue" and "green" spirals did, though.
Kent,
Just edit the image and give it a mighty zoom.
Pascal, I am obsessive enough that I finally got it figured out. I forgot to say "never mind" here, though. I couldn't get up from the computer until I saw it.
:-)
You could consider the hearts another way: as the optical illusion of a red one behind bars, but you never know which are the bars and which are the spaces.
A bit like the famous Belvedere has columns in front going (seemingly/presumedly/my head hurts) behind the further ones.
What does Mr. Belvedere have to do with this?
