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.

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

[Fetch The Bolt Cutters]

[Stacey.]

i'm not colourblind, someone in my year is...
he just sees different colours to us.

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

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

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

My music teacher in secondary school was colour blind.

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

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

[Kerry]

My OH said 21

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?!?!

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.
