Lookit!

O.o

I found the first illusion the most impressive.

Posted by mr_porteiro_head (Member # 4644) on :

The first and third are pretty cool.

Posted by Belle (Member # 2314) on :

yeah, the second one was lame. It was obvious they were the same color.

Posted by mr_porteiro_head (Member # 4644) on :

Agreed.

Posted by kojabu (Member # 8042) on :

I've seen the first one before, so the third one was definately my favorite.

Head. About. Asplode.

I don't think the first one is accurate...

I could see a difference between the swatch and both tiles, both before and after I masked it. Anyone else?

Posted by advice for robots (Member # 2544) on :

Huh.

Posted by mr_porteiro_head (Member # 4644) on :

Part of the problem with the first one is that it is take from a JPEG image, so the colors are not constant.

Posted by Dagonee (Member # 5818) on :

Yeah, they really need to do lossless compression on these.

I liked the third one. Very well done.

I made some color copies of some old placemats. The copier could not copy to the edge of the paper. When they came out, there was a 1/8 inch border of white surrounding a field of greenish-yellow. Not just a light tinting - it was like someone had colored it in with pastels.

I was very annoyed with the copier until I held the original next to it. The background was the exact same shade. Yet everyone I asked basically thought the background on the originals was white, maybe a little yellowed with age. No one saw the green in it until I showed them the copies.

Me too. I think it's worse on the third one, though.

Posted by beverly (Member # 6246) on :

Um did anyone else think the last one on the right *still* looked more yellow with the mask on? I mean, yeah the colors are closer than without the mask--but with they still didn't look the same to me. [Dont Know]

Posted by Telperion the Silver (Member # 6074) on :

Weirdness...

Posted by Bob_Scopatz (Member # 1227) on :

#1 totally baffled me. Usually, once it's pointed out, I can see that the colors are the same. OR, I can squint and focus in on just the bits that are of interest. In the case of #1, I could only do it with the swatch. It's bizarre.

#2 is obvious.

#3 is strange, but it's so complex that I find the illusion not all that powerful. The piece of interest is too small a bit of the entire graphic.

But still, fun stuff.

I love human perception.

Posted by Sid Meier (Member # 6965) on :

i think the first one was a fake, I noticed it chnage colours as I moved the swatch.

Posted by Sid Meier (Member # 6965) on :

woot I got the last post again!

Posted by Fusiachi (Member # 7376) on :

Maybe consider printing it out and cutting out the swatch to see if you don't believe?

Posted by tt&t (Member # 5600) on :

Huh. The first one looks the most different to me - had to use the swatch. But the other two, I could see the colours were the same without the mask/swatch. Weird.

In the third, it says one looks grey and the other yellow -- which one is supposed to look yellow? Both look grey to me.

Posted by ClaudiaTherese (Member # 923) on :

Very cool, rivka.

Posted by mr_porteiro_head (Member # 4644) on :

In the third one, the left cross looks purple while the right cross looks yellow to me.

Posted by ketchupqueen (Member # 6877) on :

I'd be interested to hear from some color-blind men (okay, or women, but it's so unusual) about the last one.

Posted by mr_porteiro_head (Member # 4644) on :

I'd be even more interested in hearing from some tetrachromates.

Here's the website for the guy who actually researched the illusions. Most of them I wasn't impressed with. A couple of them it's obvious the colors change. A couple of them did impress me though.
