Colourblindness

It's on the x chromosome. Since males only have one they will always inherit colourblindess from their mother if she is afected by it, and a 50% chance if she is carrying it. So you colourblind guys all know who to blame for it. ;)

I can only imagine what it is like living with colour blindness, I mean not being able to appreciate the little things like the cute red flushes on a girl's cheeks, tell if some fruit or meat is ok to eat by the colour, traffic lights. I suppose you get used to it and never knew what it looks like for real you can't imagine the beauty of the colours of the world.
 
Something that is a dumb childish wonder within me, relating to colour perception is this; how can we know that what I see as blue, is the same as what you see as blue?

I realize there is probably a simple scientific answer, but it's just one of those things you wonder.

The cone cells in the eyes respond to different frequencies of light. If you shine light of a blue frequency in the cone cells of 2 different people they will both send the same impulses.
 
I think some people are getting the wrong idea about colourblindness.

You guys are missing out, red is a nice colour.

I'm colourblind. I know what red looks like, I don't see it as a grey colour. Seems like you're making it out as if I can't see red flushes on a girls cheek. And i'll assume that most other colourblind people can see it as well.

And traffic lights? I've never heard of anyone i've met who is colourblind who has listed traffic lights as being something they can't tell apart.

Just sounds too similar as to when people do the usual of pointing at a field and asking what colour the grass is when they hear i'm colourblind.

Ah right cheers, I thought it would be something like that.

OK, I may have put it wrong. Yes I suppose you can tell when the traffic like changes, and the flushes on someone's face but I am trying to say is i would be gutted if I can't see all the colours and appreciate them. I am sure you can tell the differences but there must be a huge difference from seeing difference shades of a tone than actual colours.

EDIT - Correct me if i am wrong.

How do you know what red looks like as you've never seen red. You obviously see another colour or a different tone of red or some colour but not truely red.

Well I wouldn't know if i'm seeing truely red and I never will. The only problem I have distinguishing colours will just be particular shades, or sometimes depending on the lighting of a room i'm in i'll find it harder to tell the colour of a particular object.

A good example was the other day when a friend phoned me saying she left her hat here and I was looking about for it. I found a hat and she said it should be it, it's a dark red one. And I found it too hard to tell what colour it was, it was just like confusion in my brain!

It seemed to be telling me it could be any common problem colours that were close to brown. If I watch a sunrise or sunset or i'm just somewhere nice I can appreciate the scenery and colour plays a part in that, I don't think it'd be a massive difference if I wasn't colourblind but then again I can only guess.

Arrghh. I'm colourblind but not in the full sense of the word. I can tell you what any colour is... Unless like me227 said, it's in a dark room or mixed up in a pattern like those dot tests. Other than that, I could tell you the colour of anything you point at, and nobody would know the difference between my red or your red, we both see red.

I hope they cure it, you will like.

But I guess you get used to it. I am not perfect, quite short sighted.

And I can see most reds just fine ;)

That's an excellent example, and can relate very much to it, being red-green colour vision deficient.

For me there are shades of reds, greens and browns that look identical, like a sort of smudgy brown. Non-colour vision deficient people would be able to tell them apart, but I cannot.

In the real world, does it bother me? Sometimes. There are times like when I go to the bottle bank to recycle wine bottles, and I can't tell which bottles are green and which are brown.

I also wonder sometimes, when walking in the countryside in Autumn, and someone says "just look at all those colours of leaves on the trees", I have to wonder how many more shades of colour other people can see, and how much more beautiful it would become.

Has anyone actually tried the Chromagen lenses? (http://www.dyslexia-help.co.uk/chromagen_colour_deficiency.html)
 
Gaming with colour blindness is a bit of a mission, COD4 grass.....sniper suit.......nightmare :D


I game by movement mostly, if it moves 50m away I see it lol.......

I could see red flushes on a girls cheeks, and have no problem with traffic ligths as they always go in the same order ;)

Funnily enough I was talking about colour blindness with my mum the other night. I have two brothers and I'm the youngest; I also have the worst colour blindness. She remembered one particular occasion when she, my dad and my two brothers were driving along in Scotland.

It was a late Autumn day with the sun just starting to go down, and she and my dad were astounded at the beautiful range of golds, greens, browns, reds, oranges from the stunning vista of the valley. She turned to us three in the back to ask what we thought of the scenery, and were like :/, it's just a big greeny browness mum! :)

She said that from that moment she felt really sad that we would never experience all the colours of the world. :(
 
Tbh, it looks terrible to be colour blind to me, and more terrible a colour blind will never know how it ''really'' looks like wich just seems odd me, makes me think if the colour blind person could even imagine how red really looks like.

Very happy with my eyesight now and feel sorry for people that are colour blind :(.

Yes but some do, and if you're colour blind, how do you know how other people (with good colour vision) see the pictures ?

No need to feel sorry, it's not a handicap or anything! :)
