I found this great optical illusion earlier

and before you load photoshop/psp they *are* the same hex values..

I'm now going for a lie down :cool:

feel free to post equally weird optical illusions.

DRakE · 15-01-2003 7:28pm

lies.

Zyox · 15-01-2003 7:44pm

not lies

seen it before and tested it before
pretty cool

id like to find out why your eye see's it as different. if anyone has an explaination, or even a theory, please do post.

That is crazy !! I have to say i thought it was Bo**ox. So I DID check it out in photoshop and they do have the same RGB value, amazing.

Neil3030 · 15-01-2003 8:07pm

Yeh me too. I went one step further and here are the 2 squares wothout the letter or the rest of the board

Trés Feakeh!!

Caesar_Bojangle · 15-01-2003 8:16pm

Not really, its caused by the vague shadow given off by the green cylinder.

heavens, the boy is right!

Practical · 15-01-2003 8:35pm

lol I showed my dad who is a printer and he thinks it bullsh!t , Can anyone give me proof so I can prove him wrong

noog · 15-01-2003 8:37pm

print it and cut out the squares...

Victor · 15-01-2003 8:52pm

The trick is your eyes think all the "black" squares are the same black - when they aren't. Only the difference between black and the adjacent "white" (actually grey) is the same. I suspect colour blind people may see it "better" than other people.

I present to you definative proof that the squares are in fact the same colour:

You can literally see the colour change before your very eyes....

Jasus, that's something alright.

[CALIBUR] · 15-01-2003 11:05pm

wha?

deezoid · 15-01-2003 11:33pm

Whoa! Thats some freaky **** all right!

Gordon · 15-01-2003 11:43pm

Thats very good. Must be something to do with our logical part of the brain.

I don't think so, it's more primitive than that. Our eyes are saying "Black and white" when it is actually various shades of grey.

Personally, I prefer http://www.eduygeox.com/~jaca101/www.jaca101.com/opticaleffect.html

kamobe · 16-01-2003 1:08am

So they've clearly tricked us. That square *should* be white to keep the pattern consistent. So they've used the shadow to trick us by darkening all the squares around B. Thereby making us think that it actually is white.

Our mind is seing the pattern that SHOULD be there, but isn't.

Samba · 16-01-2003 2:42am

That is precisely it Kamobe, try to put your fingers covering most of the other squares and you see it immediately.

Thorbar · 16-01-2003 2:52am

Liquid generation have a good collection of optical illusions here.

gogo · 16-01-2003 10:22am

Tizlox, I am sitting on my own in the college library (loner, i know) and after screaming out loud.
The fuping shame.
Thanks.:eek:

gogo

deezoid · 16-01-2003 11:03am

Thanks Tizloz. Entire office didn't stop to look at me as I shrieked like a girl. and fell backwards off my seat!

Thorbar · 16-01-2003 1:56pm

Tizlox that site installed some sort of spyware on my computer thru ActiveX and I'm having a nightmare trying to get rid of it. I suggest noone accepts the ActiveX files from that site.

R.O.F.L

still, the .swf isnt much of an illusion

^CwAzY^ · 16-01-2003 7:48pm

Wow that's really cool. I didn't believe it until I printed it out and compared the squares. Excellent!

acid · 16-01-2003 9:09pm

here's a simpler illusion thats a bit similar - how many colours do you see?

my fav ever illusion is this one by Escher -

wiensta · 16-01-2003 9:24pm

3?

monument · 16-01-2003 9:44pm

2?

acid · 16-01-2003 9:53pm

3 including white - its just that at first glance there appears to be 2 different reds/pinks, thats all.

heres another of my faves - would you trust this person? -

Gordon · 16-01-2003 9:55pm

That must work on the same principle as the first illusion. (2 right?)

Tellox · 17-01-2003 4:54am

I dont trust liars.
Also, there are many different colours in that picture, zoom in far enough and you can see them, or you can open psp and get all the different RGB values. Theres defintly over 3.

I think acid meant the attached picture not the one below:

Which leaves me with one question: what optical illusion should I be seeing in the picture above??

just try to follow the water...
