Colour Blind

[InOne]

Is anyone on here colour blind? I've never really imagined what it would be like. I know it's not as simple as it sounds, it's certain colours or something.

[Patrick]

My mates dad is, I think everything is in Black and White?

[Fetch The Bolt Cutters]

i know somebody who is colourblind but its only with red and brown

[Fetch The Bolt Cutters]

nah its not black and white

[Stacey.]

i'm not colourblind, someone in my year is...
he just sees different colours to us.
like, purple is red to them, for example.

i imagine the only time being colour blind would be a problem is when a bomb is about to go off and they have to push the red button or something

[Tom4784]

My music teacher in secondary school was colour blind.

Well it limits you somewhat, for example one couldn't be a pilot if they were colour blind [ty Little Miss Sunshine]

[Kerry]

My bloke is. He struggles with reds and greens mainly. Wouldn't say it affects his life so much but he struggles when playing some computer games or using graphics and often asks me what colour stuff is

It's usually subtle. Glaring colours such as that are not usually a problem

[GypsyGoth]

If someone see blue as red (for example) all their lives, how do they know they are colour blind?

Something I always think of too. Plus how scientists come up with how dogs or cats see.... How the hell do they know?!?!?!

They probably just make it up :D

[Kerry]

They probably just make it up :D

:D

The best I've heard is that cats and dogs don't sleep (fully) or dream.

They seriously need to see my two..... They're dafter asleep than awake and thats saying something!!

There are several types of colour blindness, the easiest way to diagnose it is by the use of the Ishihara test, a series of pictures where dots of one or more colours forming a number are featured in dots of another colour: In the piccie below normal perception should show the number 74, some types of colour blindness will show it as 21 others wont see the number at all.

People who suffer from colour blindness dont necessarily see reds as blue or greens, shades of the two different colours appear to be identical.

Colour blindness could potentially be dangerous where reaction to colour signals need to be interpreted quickly and accurately, for example train driver, pilot etc. Certain types of colour blindness can stop you getting a driving licence in some countries. Also electriccians can be decertified if they have problems with blue green and yellow. It can also be limiting for artists and other involving the use of colour.

I saw the number 74 but saw 71 at first. Only took a second though to focus.


Gonna test my OH now :D

[Kerry]

My OH said 21

[GypsyGoth]

My OH said 21

Wow! I see 74 clearly.

[Kerry]

Wow! I see 74 clearly.

He looked and said 21 straight away even though he knew it was a test. He's done loads similar

It's never bothered him. But he has to mention it with certain jobs and stuff

[GypsyGoth]

But I can't see how you could make the base stroke of the "2," the colour looks identical to the rest of the circle to me.

[Kerry]

2?!?!

[GypsyGoth]

2?!?!

I mean the way your OH sees the first number to be a "2"

[Kerry]

I mean the way your OH sees the first number to be a "2"

Oh I see. It's more the 4 that confuses me as that seems as plain as day to me

[Shasown]

The two figures are made up of several green shades if you have a problem with certain shades of green the 7 takes on more of a 2 shape without the base line, think the brain just recognises it as a two by the fact its more round at the top, the shadings in the 4 are less subtle with the darker green making a 1 shape and the lighter greens filling in the rest of the four.

[GypsyGoth]

Thanks Terry :thumbs:

[Shasown]

Thanks Terry :thumbs:

Your more than welcome.

I have a friend who struggles to distinguish between red and green; I distinctly remember in the early years of secondary school, his colouring pencils had labels on them saying what colour they were; and then a more recent, funnier memory of him trying to roll weed and tobacco and messing up the quantities he was putting in because he got confused between red and green, haha.

[setanta]

I have a friend who is quite coloured blind and yet, he's a very skilled artist lol. More into model making though.

[Crimson Dynamo]

Spaceman came down to answer some things
The world gathered round from paupers to kings
"I'll answer your questions, I'll answer them true,
I'll show you the way, you know what to do"

Who is wrong and who is right?
Yellow, brown, black or white?

Spaceman, he answered,
"You're no longer mind
I've opened your mind
You're now colour-blind"

When I was little, at school we had a colour blind test every year for a few years.

That Ishihara's one, ( I did not know his name until Showson mentioned it).
We were given 5~6 pages and had to read numbers.
Among them I could not identify anything number or any shape.
It was specially made for a colour blind person and if anybody managed to be able to read it, the person was a colour blind. (I did not know it then)

(Also we had a blood test so that everybody knew what type-group we were. I am a blood type A.)

Is anyone on here colour blind? I've never really imagined what it would be like. I know it's not as simple as it sounds, it's certain colours or something.

I'm colour blind and its said something like 1 in 20 white males have some degree. something like 1 in 200 women (so i heard) but it can show up in other groups too.

Right, it is usually certain colours and then that can vary in difficulty depending on light and textures.
My eye doctor dude explains it as a genetic mutation where I have less 'rods and cones' (or less of the ones I would want heh).

The common one is 'red-green' colour-blindness although some can have the rarer 'blue-yellow' types.
Mine is basically red-brown-greens that I cannot fully distinguish.
For example:
No, I cannot see any sort of numbers in that graphic posted here.

People have asked me 'what its like' but you have to remember I was born this way and don't know any different.
Had I not been caught with a psychedelic colouring book (to their eyes) or coming to school with mismatched colours of socks I would not know any different.
I may still wonder if all you people are colour-blind and I am the one seeing things right?
;)

But seriously I do have problems with traffic lights sometimes - which is a little scary. I see your 'green light' as a white light and sometimes I cannot see the 'red light' at all.
For some reason lights in the UK seem easier to distinguish than in North America so maybe the UK has better technology for this?
At stop-lights I am not looking at the colours but at where they lights are in order of 1,2,3 on the panel.

Sometimes I get screwed on instructions (elevators or whatnot) to 'press the green button' which may give me (to my eyes) a choice between several 'green buttons' lol

I cannot do electrical work (or can I?) or most things with complicated colour codes.
Colour-coded maps like you see in train stations, bus stops etc... often just a blur.
Those colour-coded types of surveys in newspapers or on television.

Generally speaking the effect for me is that all colours have a little 'beige' tone mixed in.
Except Blue and Yellow.
Blue i find a little more difficult and probably because its so frequently mixed in different hues and tints.
Pure yellow is like an outstanding electrically charged highlighted neon sign.

I should mention I can see black and white perfectly. I'm told they are not colours heh.

Funny story.. when I was a little boy around 4 years old my mum would find collections of yellow items in my room. shampoo bottles, bottle caps whatever.
Its seems I figured yellow items were magical and special and of course I can spot them easily.

I can see 'shades'. Its how I get through life. Faced with the choice of the green or red button I assume the darker one is red.
I guess that dark green is probable considered brown to others.

It is true that you cannot become a fighter-pilot or sniper if you are colour-blind. So they say. I wanted to join the military when I was a teen but someone told me I'd get rejected.
(imagine the chaos with a weapon and instruction to shoot the 'red targets')

I once met a guy who had comparable colour-blindness and also did not know any different.
He invested in a special pair of custom-made eyeglasses that cost something like 12,000 pounds and took ongoing tests and retests to eventually somehow trick your eyes to see colour properly.
He described it like this:
- As if you were watching the old black and white movie 'Wizard of Oz' and then where the scenes are suddenly in big bold colours.
(keep in mind we can see some colour),
but,
to him it was like that with 'regular vision' and then when he put the glasses on was like 'SUPER COLOUR EXPLOSIONS'.
It made his regular vision seem like 'black and white' in comparison.
He described having actual 'emotional problems' and treated the glasses like a drug or something he only used for special occasions or else he couldn't do his job.

I think I would rather just carry on not knowing any different.

[InOne]

Ahhh nice explanation! Yeah, I never thought of the people not knowing any different so not really being able to explain it at times.

I enjoyed reading that - very informative! :thumbs:
