MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
Hoping TJ might come on and argue that actually no, it's white.
I want my baby back.
racist
might come on and argue that actually no, it's white.
I thought pedantics was very much your style too ? 😕
How's the argument on the other thread between you TJ getting along btw ? I haven't really been following it much recently but I see you're both still at it ......... who's winning ?
who's winning ?
No-one. TJ's there.

So, the pot's black and the kettle's black, right? 🙄
I'd say it's more like a very dark grey myself.
Isn't [b]true[/b] black sort of... the lack of light.... or such tiny amounts of light such that your eye can't detect it ... so black could just be tinsy winsey anounts of white.... just a matter of scale really!!!!!!!!!
What can I do?
'Cos I I I I I'm feelin' blue.
Probably fairer to say that grey is grey.
(Since you went away-ay-ay).
if x = y
then x2 = xy
sub y2 gives x2 -y2 = xy - y2
divide by (x-y) x + y = y
and since x = y we get
2y = y
ergo 1 = 0
white = black + 1
white = black
It's not black unless it's priest black. Anything else is just very dark grey.

And this is what happens when you divide by zero. 😉
There are different levels of blackness. Some are quite blue.
Oops, misread thread title 😀
Interesting image.. but it still works if you cover up everything apart from a thin strip with the three squares in it. Only when you cover up the inbetween 'white' square do you resolve them as the same shade.
Very interesting image. I actually put it in paint and joined the two squares and it still looks like different colours, just graduated from A darker to B lighter!
Points A and B are actually the same shade
If that is true, you are a witch and should be burned at the stake.
But I don't believe that it is true.
Edit: Unless the reference point is the writing itself, in which case I could be persuaded
Cut two holes in a piece of paper so you can only see bits of the colours - they are the same.
Or just use MS paint to examine or chop up the image.
Black can also just be an optical illusion...
that is a proper head mash!
That really is odd! Fascinating what the brain will try to tell us it is seeing.
It's just developed a load of shortcuts to save us time. You can catch it out occasionally.
Nice way of putting it. 🙂
worked with researchers a long time ago, doing stuff with [url= http://en.wikipedia.org/wiki/Hemispatial_neglect ]spatial neglect[/url] patients. It revealed some really weird shit about the brain.
Whoah!
So, for example, if patients are presented with an upside-down photograph of a face, they may mentally flip the object right side up and then neglect the left side of the adjusted image.
Crazy.
Anyone ever see that programme where people wore upsidedown glasses - after a few days the brain adjusts to put everything the right way back up.

No, but I drank too much scrumpy once.
Yes.
Related - whenever I'm driving in a country that drives on the right, I get my left and right mixed up. Possibly because I'm thinking inverted, possibly because I'm so used to turning right = crossing traffic.
Fuligin - The colour darker than black.
clubbers second image does some very odd things to my brain.
When I brike my right collarbone and had to go left handed for a while, I kept getting my left and right mixed up and even had to think twice about which side of the road to drive on (I learnt amazingly quickly I could do almost everything left handed with a little practice, even writing albeit slowly)
Is black actually black or is it an absence of colour?
Yes - it absorbs all frequencies of light and therefore is is an absence of light. If talking about subtractive light that is. If talking about additive light (ie pigment) then it is all colours (add cyan, magenta and yellow together in equal measures you get black).
If anyone is interested, there was a BBC Horizon program about visual tricks like the one m_f posted above, and they have something on the BBC website which has a few optical illusions on...

Black is also the absence of reflected light...
For example, if you shine a torch down a bottomless pit it will still look black, as there is nothing for the light to reflect off. This means that you won't see light travelling through a vacuum unless you interrupt it.
