Colour blindness stuff.

In April of 2001, while discussing with a close friend of mine Nick Yee, who is red-green colorblind, the differences in our subjective visual experiences, we realized that color vision is not an unequivocal gain. That is, in some situations, he could perceive variations in luminosity that I could not. This difference got us to thinking whether we could design a "reverse" color blindness test - one that he could pass because he is color blind, and one that I would fail because I am not.

the second one is totally clear for me. True story.

I like reverse tests way better, 'cos that way I'm winning, like.

Moar.

:smilie4: I'm not colour blind.

me neither.
My dad is though.

What the pattern in the second one that I can't see?

just a random pattern nothing in particular.

It's a

1st one is a

Damn I am colour blind. :pinch:

6, 0, 56?

Squeamous you're also as blind as everyone else.

And the blindness achievement award goes to the girl playing with her internets while the hubby paints over-sized LOTR dolls. :hooray:

6, o and NO is what I'm seeing.

I'm not strictly colour blind, though, I see all the primaries but nuances screw me over a lot (it's cos of a virus, not the usual thing). I could be fucking the last one up.

Nope, it's NO :smilie4:

Wait :pinch:

I see what you mean now..that comes through a little too. Tbh I think those things aren't very good because I have perfect vision. Funny how it's usually men who are colour blind tho'.

Might just have to do with the contrast on your monitor :idunno:

Women can have it too, but it's way rarer, it's genetic, like, and usually dormant or recessive in people with xx for some reason.

You can also have it temporarily if you're ill or pregnant or something.


Still, it's usually women wot have their periods, so it's a fair trade. Though my outlook might be different if all I saw were shades of brown, like.

I couldn't really tell what they were, but I could sort of guess, if you know what I mean :unsure:

The first and the last aren't uber clear to me, like. But they aren't hard to make out.

The middle one is so clear I had a hard time accepting that others can't see it.

Maybe you've all had some bad eye-aids like wot I did, so your colour-perception is fucked now, same as what happened to me.

Mine started out perfect, you know.

:smilie4:

Both of my brothers are color blind, one seriously so, the other slightly. As the chaps said it's much more common in men than women and is almost certainly passed from your maternal grandfather.

I was tested in school and at that time, though it was rather a long time ago, I showed no signs of colour blindness. My brother who has it to the max cannot tell the difference in colour between a red andgreen traffic light. True Story.

Although the red one is usually at the top non?

I can see the 6 and the 56 but the one in the middle looks like a map of the Milky Way - I see nothing but randomness.

It's not really a 56, lolz.

I can see the NO if I sort of squint but my eyes prefer the 56 - can see sod all in the middle one - how do people get 0 out if that - there is a band of star dust going from bottom left up to top right?

I thought I could illustrate by turning it monochrome, but it turns out the pattern just diappeared for me, then. Odd.

It's not so much an "0" as it is a perfect circle.

As for your 56, I can't see that at all.

well i am colour blind.

i see 6 a circle and NO in the 3 pictures, all as clear as day.

the usual colour blind tests i get to the 3rd one and cant see jack shit after that lol

and yes, it is from the grandfather, it always skips a generation.

Turning up the contrast to the max, and the brightness up slightly will reveal 2 and 3, but whatever I do I can't make number one much clearer :blink:

No and a circle again, but even more clearer now that in the 1st pics lol

It's people who are colour blind who are more liable to see them. Your eyes can differentiate between the different colours, theirs cant so they see similar colours or shades. This makes up the numbers or words that you can't see. You can't see them because they aren't really there. Sans the condition obviously.

Bearing in mind that there are different kinds of colour blindness. It's Red/Green in my family. My brother for example always had to ask someone to check his socks because he could see a pair when in fact they were a different colour.

There are other tests where you will be able to see numbers which they cant, because of their condition again. You see a number but they don't because the colours which you see as different and make up the number, they cant see that difference.

That's my understanding anyway. It may obviously be pish.

Try this test, it tells you what you should see depending on if you have colour blindness.

http://www.kcl.ac.uk/teares/gktvc/vc...ess/cblind.htm

It covers both types of tests. Those you should see and those you shouldn't.

Yup 24/24 normal.

Now I need to work on the rest of me.

I'm afraid I'm going to have to leave you to your own devices on that one mate.

According to one pic I'm red-green colour blind, according to the next I'm not. I'm not getting near 24/24, but according to some plates I'd be perfectly normal. I'm in serious trouble when it comes to most of the non-specific plates, though. I've also got mild protanomalia, whatever the fuck that is, according to one plate. And I'm not seeing any of the numbers that aren't supposed to be there :blink:

It's prolly 'cos I don't have a normal kind of colour blindness, though.

I like the ones with figures normal people can't see, 'cos they give you an inkling of what it's like for for me trying to make out numbers on the regular type of test, after a fashion :happy:

Was frustrating as fuck at first when my eyes stopped working properly, like.

Although I'm right normal when looking at those pics in the last test.

I can understand how it would be really frustrating, like I said my brother has it really bad. The red and green on traffic lights look the same to him, colour wise, so he has to judge by whether the top or bottom light is on. Which means at night he has to be close enough to work that out.
