Colour Blindness

OutlawPete

The Dyslexia threads lately have thrown up a few users that I was surprised to find to be Dyslexic and got me wondering how many people are colour blind as I rarely meet people who are.

I am Red Green Colourblind.

It has restricted me bigtime in life as so many things I was interested in studying, I had to pass on. Photography, Guards, Graphic Design, Pilot (don't laugh, I could have been one ).

When I was growing up, Snooker was always the thing that I was slagged mostly about.

Green, Reds and Brown always looked the same.

If they were extreme shades I could make them out, like Brown Sauce, Red Fire Engine and Green Grass are easy but once the shades change from the obvious, the colours just merge and you can't see any difference.

Blues and Pink can also look the exact same.

So, anyone else Colour Blind?

Here's a test if you've had doubts.

I can vouch for this test 100%, as I can see only three of the numbers

There are different forms of colour blindness? I know one of the girls in here in work cant tell the difference between navy and black but I didn’t know there were "red/green" types. That’s just mad. Ted!

I can confirm that the above video isn't a shock-scare one or a rickroll

I remember doing these in primary school, we all queued up, went into the staff room and were given an injection, a sugar cube and were asked to look at some of these tests and call out the number we saw. I had no idea what that test about, I didn't even know at the time that there was anything to it. I've no colour blindness thankfully.

I think the Red/Green thing is colourblindness

Deep Navy & Black wouldn't really be teh same.

Yup.

Navy and Black for me too.

I actually bought one of those 'Black' Army woolens Rockers use to wear.

Wore it out, thinking I was the biscuit and my mates tore into about it being Navy

Pffft.. Hell no.

If I was colourblind I wouldn't be perfect in every way.


And I am.

NothingMan

I feel your pain Pete. Never knew I was until I saw one of those tests (I assume it's the same, youtube is blocked in work). Everyone's saying that there are numbers as clear as day in the patterns and i'm going mental thinking they're winding me up. Not sure what type of colour blind I am. I can see that there are different colour dots in the patterns if I concentrate but they don't make any particular shape that I can see. Quite scary really.

Then again, who's to say if what I know as green is even remotely what you see as green! How could you ever know?

Thats a genetic deficiency in men.

My dad's colour blind, but I'm not.

Apparently, it's passed down through females, but it's more common for males to be affected by it.

Sam Vimes

No

I'm colourblind. Makes it very difficult to be racist but I just ask someone if they're black and then start hating them if they say yes.

Because I can differentiate it between red and brown.

That last test, the 2 or 5 - I couldn't see either! :eek:

Sam Vimes

No

I'm told this is the best test for colorblindness. I fail it

Nemanja91

No

Found out when I was in 6th class, mainly red/green and brown, hasn't affected me much except the fact that the only job I wanted was to be a soldier so I couldn't pursue that career. Very few times when I get mixed up with colours though, the last of which i was playing pool and i thought that a yellow ball was the white and I hit it, but that could have been more stupidity on my part. A very annoying thing though is when people find out you are colourblind and they ask you " What colour is this?"

stovelid

I know this sounds dumb, but if to fail a particular test, does it mean you just cannot see the number at all? Apart from the last one, obviously.

What if you can almost see, for example, confusing 8 for 3 or whatever?

Does that just mean that the blindness is on a spectrum, for example, nearly OK right up to fully blind, if you get me?

Sorry if this sounds thick.

Board-in-work

You can still qualify as a pilot if your are colourblind. There are a couple of different tests other than the dotted pictures with numbers in.

I've been labelled colourblind since school.

I just downloaded the colourblind tests from the internet - there are only about 12 or so of the plates. I memorised them by shape - ie what shape I saw in them - and its not a problem now.

I qualified as a glider pilot many years ago - and I work as an electrical design engineer. I'm not saying my designs win any colour awards - but who cares.... !

DazMarz

Nope, thankfully not colour blind. Cos my work as a poker dealer would be cut short if I was!!!

€5 chips are red
€25 chips are green

Make a mistake with them, and it could be very, very costly!!!!!!

I know what you mean. I can see that there are different colours on the picture they just don't make out any pattern to me. Do some people not even see the colours?

I doubt it. I'm the same as you, there are a load of different colour dots but no pattern. I think there are some who can only see black and white but they're very rare.

Remember a few years back watching two friends of mine (brothers) who were fixing a motorbike, and because they are both colour blind, they nearly came to blows arguing about what colours the wires in the electrics were. I had to tell them what colour each wire was so they could they could wire it up correctly, so they didn't wire it wrong and fcuk up the bike...... Think they should have left it to the experts:D

Is it true that you can't be an electrician if your colour blind?

NothingMan

No

But who is to say what I know as red is what you know as red. Maybe we see the world completely differently. When I see a red ball know it as red because that's what I know that colour to be but maybe in your eyes you see something i'd call green but you know it as red because it's always been red to you.

No, I'd be fairly confident that there's a scale of colourblindness. Even Pete notes that he's OK when the colours are strong, but it's harder with shades.

The tests in the video are designed to be difficult - if the numbers had a stark contrast to the background, then people with only a mild colourblindness would still be able to see them.

There is one test in there, where it would be easy to confuse the 3 with an 8, but if you look a little closer, you can clearly see the 3. A colourblind person would have difficulty distinguishing any kind of shape from the background.

No, not stupid at all.

I can just barely make out the 29 for instance if I try really hard.

My brother is Colour Blind also and he cannot see somethings in tests that I can.

There are definitely different levels of it, that's for sure.

I've had that thought before and forgot it. It's brilliant.

Grass is green, but I could see the grass as red yet call it green as that's what I call it. F*cked up. We'll never know!

I don't know about Sam, Nothingman and others but I have no problem with differentiating between those shades.

If someone puts a handful of grass against the side of a Fire Engine, I can tell the difference.

Then I could go playing snooker and can't find the green amongst the reds.

It's all about the shades for me at least.

I always thought it'd be funny to teach your child all the wrong names for colours so everyone will think he's colour blind.

Same here. Grass and a fire engine look totally different but in a casino I've had to ask for different chips at the roulette table because I couldn't tell the difference between mine and another guy's. Only once though so it's usually fine. Same with snooker, usually it's fine but a few times in bad light or if a ball is faded I can't tell the green from the brown or reds

Me too! Green-Brown, Red-Green and Blue-Purple (less so)

They caught it in first class when I couldn't stop drawing brown grass in my pictures. I haven't been too limted by it though, the yellow stripe in the earth wire helps a lot.

Snooker is still worst, I have to have most of the balls pointed out before I take a shot. Trivial pursuit also - matching the answer categories. When I produce charts in stats programmes I have to make sure there aren't any overlapping colours, and it makes it hard to read things like trend diagrams with multiple colour coded lines.

Ah, so did I

I once drew the Incredible Hulk brown

I also see no difference between Amber and Red on a traffic lights.

It doesn't matter unless there is no streetlights and then I just have to treat Amber as Red.

I have often wondered why they didn't choose Blue instead of Amber, I could tell Blue and Red apart far easier.

Same here (lights), I have to do them by order. Filter lights were confusing at first because I couldn't work out if the top light of the two was stop or go

Not sure, I hope someday that I'm upset that I can't get one though, it'll mean good things have occurred, a lotto win maybe

Can one of the colour blind people tell me what this says? Apparently its a reverse test that only colour blind people can get.

Maybe, it also could be 'H6'.

It's VERY hard for me to see at least.

Always felt sorry for the brother in the film

"Little Miss Sunshine"

when he finds out he's colour blind!

nucking futs

This thread reminded me of a funny story about one of my class-mates

In 5th Class we had the usual eye exam. Anyway to test for colour-blindness there were half-a-dozen cards with a circle drawn on with an opening at either end. The idea was to follow the path out with your finger, obviously the idea being that if you're colour-blind you won't be able to distinguish the line from the background. A lad in my class didn't understand what he had to do so he just followed a straight path from one side to another so the examiner thought he'd failed each one

The Recliner

I think this t-shirt sums things up perfectly

Prof.Badass

Yeah, it's all down to the colour-detecting cells in our eyes. In humans there's 3 different types (called cone cells) which pick out red, green and blue...then our brains take data from all 3 to form the range of colours we see. With colourblindness one or more of these cones aren't working properly, giving the person a smaller range of colours.

What's interesting is that most birds have 4 colour cones (known as tetrachromacy) which makes them able to see a whole range of different colours, even extending into the uv range.

Then you have some animals which have 5 :eek:, such as pidgeons and butterflies. So i guess we'd all seem colourblind to them.
I realise this post probably seems a bit weird, but i wanted to share about tetra and pentachromacity as i think it's quite amazing to think how other animals experience the world.

That T-Shirt sucks. I bought it from T-SHirt hell and I couldn't read it on the site but what was delivered was of such low quality that a fully blind person could read it nevermind colour blind. I complained but they just said I must not be colour blind. Bastards!

I've got a bizarre form of colour-blindness which officially comes out as 'red/green' in the dot tests, but I find my real problem is with dark hues of blue and red. Didn't know a thing about it until I took the medical for the FCA and was told I couldn't drive for the Army. (But it seems nobody bothered to check, and I got my AF154 anyway). I can pass the D-15 graduated colour vision test, it's that damned 'spot the number in the dots' test that throws me.

hasn't affected me much except the fact that the only job I wanted was to be a soldier so I couldn't pursue that career

That's one of those bizarre things where people don't learn from history. In WWII, colour-blind persons, particularly monochromatic (i.e. no colour vision at all, they can only see in greyscale) were specifically sought for recon and photo-imagaery analysis jobs. Fully colour-capable persons are far too used to cheating and just looking for colour differences, whereas monochromatic persons instead look for contrasts and shapes: Much more useful when you're trying to spot green camouflaged vehicles under green netting on a green background.

My arguments did not hold up, unfortunately, when I went to the US Army recruiter, and was told I couldn't be a tanker or cav scout, as full colour vision must be a requirement. (I have heard instances of some colour-blind tankers not being able to see the red laser-projected reticle in the tank). (They also said I was too tall to be a tanker. Harpumh). But where there's a will, there's a way. To be an officer in the US Army, you just need to be capable of distinguishing the seven colours on a military map. If you can do that, then once you're in the system, they don't check.

I was also able to obtain a First Class Airman's Medical Certificate (Airline pilot standard), the requirement is not 'fully colour capable' but 'must be able to perceive the colours required', which generally means red, blue, green, white and I think yellow.

My dad and one of his brothers are color blind. One of their friends gave them red golf balls as a joke and they were always losing them.

They would have to get the non-color blind brother to find them all.

I can make out a no in it too. I'm not colour-blind though apart from a "slightly deficient green" which I assume means I can't tell the difference between certain shades of green.

Thanks for that Pete, that was a cool wee test:).

My hubbie, 2 sons and I just did the test. We all thought the 15 was 25 though when it goes misty the 1 is more clearly defined. We all also thought the 3 was an 8-though we could make out the 8 when we saw the answer. The final picture didn't look like a 2 or a 5 to any of us, if I did have to guess it was more like an 8. Are we all colour blind?:D

Danbo!

No

Yep, im colourblind too. I found out in college when a friend showed me that **** the colorblind t-shirt and I couldnt see anything funny about it. It must be mild enough for me though, I dont have trouble with traffic lights, but sometimes when I see red and green printed beside eachother, they kind of flicker. There are some shades of greens/reds/yellows that I have trouble with.

I remember telling the aul wan and she thought I was joking, and asked what colour is my jumper?? I looked at it and didnt have a ****ing clue how to describe it. After a pause from me, she said "its taupe!", resulting in most of my family laughing at her.

Dunno about that, pilot maybe not, but gardai can be colourblind but cannot drive, although I think they have a second level of testing beyond those disc tests. Im an architect and have never had a problem with it in work, ie someone finding out/commenting on anything, and I mainly work in the visualisation side of things. Also into photography as a hobby.

You could be in the army pete, apparently (probably a myth) camouflage isnt as effective to colour blind people. Dunno how though.
