Colorblindness

[Fax Celestis]

I've been colorblind my whole life. And suddenly, someone does a test (http://dsc.discovery.com/news/2009/09/16/colorblind-monkey.html) and there's a chance of me someday overcoming it.

I am seriously floored. It's something I never thought would happen.

[Player_Zero]

I wouldn't put an amazing amount of stock in 'what some internet article says about some experiment carried out by some scientists on monkeys' to be quite fair.

Be floored when they successfully globalise an affordable cure for colourblindness. Currently you should approach with cynical skepticism.

[Icewalker]

Fully colorblind, or to what degree? That's really cool, that we've gotten to the point of changing genetics to fix colorblindness...Good first step. :smallamused:

This is one case where scientists were bored, looked at the impossible, and said, "why the hells not?" And it just so happened that they managed to go beyond it.

Thus my new saying: "If necessity is the mother of invention, boredom is her half-crazed split personality." :smalltongue:

[Rutskarn]

Indeed. Often, these experiments do go south. Not saying you should be consumed with despair or anything, just don't get too hyped up?

[Thatguyoverther]

This is awesome.

I wonder if this could be used to extend color vision beyond the normal scope. I could use a few more colors in my life.

[Icewalker]

Actually, that's an interesting point, as we have green, blue, and red color receptors in our eyes. I do believe (although am not sure) that some animals have others, and am curious as to what might happen if this method becomes viable in humans and could be used to add more...:smalleek:

Eh, of course, I'm fine with falling back on the EyeTap and neuroscience to improve our vision into new spaces, so.

Snakes have indigo and sometimes violet receptors.

[charl]

Certain fish can see colours beyond what we can. I believe goldfish for example can see infrared. There are also birds that can see ultraviolet.

Bees can see a little in the ultraviolet spectrum. There's a color which we can't see called "Bee-Purple". Some flowers have this color and bees use those markings to differentiate between flowers that we could not.

I do believe (although am not sure) that some animals have others, and am curious as to what might happen if this method becomes viable in humans and could be used to add more...:smalleek:I really wish I could remember this bit of zoology properly... But this is what I do remember:
There are several well-defined degrees of colour-sight - 4, I think, or 5.
1. No colour, black, white and grey only.
2. 2 basic colours, I think. What colourblind people and things like dogs and so on have.
3. 3 basic colours, what humans and various other animals have.
4. Spectrums beyond ours, particularly ultraviolet. Bees, some birds, fish, and various other animals have this sort of sight.
I'll go look it up properly, see if I can find it.

My Boy's colourblind. It's quite interesting. Once I had something like carrots, peas, broccoli and brusselsprouts on my plate, and he informed me that there was "far too much orange on that plate". XD

edit: Wikipedia's easiest.
Monochromacy: Total colour blindness. Sea lions, whales and similar.
Dichromacy: Two basic colours. "Colour blindness" in humans. Currently believe to be so for most mammals (but research is still being done), including dogs and ferrets.
Trichromacy: Three basic colours. Humans and related primates, most marsupials.
Tetrachromacy: Four basic colours. Possibly some humans (the information on this is confusing, and I get the impression it's largely hypothetical), probably no or few mammals, jumping spiders, fish, birds, reptiles, etc.
Pentachromacy: Five basic colours. Some birds, butterflies, lampreys.

[V'icternus]

I wouldn't mind seeing ultraviolet, even if it would take a little getting used to...

Then again, I'm pretty satisfied with my vision.

Still, a potential way to remove colourblindness? That's gotta be worth looking into.

[Icewalker]

Yeah, there we go. Didn't remember that some animals would hit the infared and ultraviolet spectrum. That's where it would get very useful as an addition, not just interesting.

[Jalor]

One of my friends is colorblind, and any procedure to fix the condition would make his Computer Graphics class a lot easier for him. I don't have the class with him, but apparently he has to point to the colors he's not sure about and ask what they are. Sometimes he forgets to do this and makes something pink when it should be blue.

[llamamushroom]

One of my friends is colour-blind, too (which means he gets a little 'annoyed' when he hears Everyone's A Little Bit Racist), and still manages to ace his design and visual arts projects. If this cure doesn't fall through (I heard one of the researchers say something about "higher priorites" on the radio), Bailey will be a force to be reckoned with.

Also, if we can extend our vision to infra-red, does that mean we could see heat?

[Zeb The Troll]

This is very cool. I would totally submit to being a test subject for getting Infrared/Ultraviolet receptors grown in my head. :smallcool:

[Archonic Energy]

Anyone else thinking of the Futurama Episode with the "Z-Ray" eyes on sale down the back alleys of the streets of New New York
Yes i did just post to use multicoloured text

[Serpentine]

Um... I'm pretty sure infrared is something very different to what I posted o.O Mostly, it just means you can tell the difference between a greater number of colours. For example (that was given), if you're given two reds, you think they're different, while the rest of us think they're the same.

[daggaz]

Dogs arent totally colorblind. They are red-green color blind, which is why their toys shouldn't be painted red. yellow is far better, or bright blue. Dont trust everything you read on wikipedia, anybody can edit that, and its a common wive's tale that dogs are black and white vision only.

[Anuan]

I have a friend who is colourblind. He's a graphics artist and animator...and he's -excellent- at it :smallbiggrin:

[MethosH]

Actually some people are finding a way for blind people to see... So the cure for colorblindness don't sound all that weird. Of course it is all experimental and may depend on the cause of the colorblindness... But in about 30-50 years we may have a cure for some types of colorblindness. Probably a very expensive one. :smallfrown:

Dont trust everything you read on wikipedia, anybody can edit that, and its a common wive's tale that dogs are black and white vision only.Are you talking to me? That's not what Wikipedia says. It says they're dichromats, which means they see in two colour spectrums*, rather than three like us. You're thinking of monochromats, of which it seems there are only a few animals, of which dogs are not.

edit: Wait, that can't be right. Gonna check the page again, I think I got something wrong in that post.

*I may be getting the terminology wrong, but you get the idea.

[blackfox]

I've heard about people who have damaged eyes but working retinal nerves, like when they're missing an eye, where they have a prosthetic with a digital video input that is then simplified and interfaced with the retinal nerve, so that you get about a 20x20 pixel, black-and-white image... primitive now, but DEFINITELY promising. Dunno why I'm still in compsci instead of biomed, this is exactly the sort of thing I think is really, really awesome.

[Joran]

I have a friend who's red-green colorblind. His pet peeve is when people find out, they start pointing at objects and asking what color he thinks it is.

Race for the Galaxy is a frustrating experience unfortunately, but that's about it.

[Serpentine]

Daggaz: I think I read the bit about dogs and cats elsewhere, then went back and put it in the wrong place. Thanks for pointing out the error.

[Flickerdart]

That's cause you can use hex codes on the computer, or limit yourself exclusively to certain spectra. Hell, black and white and any one primary are all the colours you really need.

...:smallfrown: I...actually know someone who is sensitive to ultraviolet light. It's not nearly as cool as you think it'd be. He has to wear sunglasses all the time, and I mean ALL the time, even at night sometimes, because it hurts his eyes so much that it gives him headaches. This is on top of the headaches he already gets when he's not taking his medication for the chemical imbalances in his brain (unrelated to Ultraviolet vision). Which is sad, because this guy is pretty much one of the coolest guys I've ever met.

Still, this bit of information shows major promise to all people who experience color blindness or vision impairment.

[PJ the Epic]

Hey maybe they can fix me now!:smallsmile:

I have a condition that is undiagnosable (I think), but doctors recognize it as a condition none the less.

My eyes are sensitive to all colors, in a way that I see all colors vibrantly. I can tell minute differences in color shades. Contrasting colors hurt really bad, and I have trouble looking at them for extended periods of time. Also, my eyes "tire" faster when reading or looking at a computer:smallfrown:.

It really sucks sometimes.

[Serpentine]

Do you see anything in this?

[charl]

I'm a synaesthete. I hear everything in colour. It doesn't really interfere much with my daily life, though I have a hard time imagining how boring music must be to other people.

[CrimsonAngel]

^: Hey a girl in my artclass has that.

A bunch of boys (well, all except me) from my old school took an online test to see if they were colorblind. All of them think they are colorblind now.

[Zanaril]

Do you see anything in this?

How would that work if computer screens only use three colours? :smallconfused:

[Serpentine]

It's meant to be that you can tell the difference between two colours where others can't. It's not exactly that you have a whole new colour to look at. Other than that... ionno. But the page I first saw it on had an email address with "if you can see it, contact me!"

[Adlan]

I have a fun colour blindness, it's not in my eye's receptors, but in how they are wired up. No doctor's ever really explained it properly, It's more colour weird than colour blind. I see some things on tests that a colour blind person can see, and I see most things a 'normal' sighted person can see. It's mainly in the red/purple area. of colour, but as it's not really effecting me, the specialist wrote some stuff in my record and sent me on my way. I mention it when I go to a new opticians though, else they notice and send me to another specialist.


Co incidentaly, my CSM mentioned having a colour blind guy being a good thing in your squad, as he was better able to spot cammofaluge and the different textures of an enemy trying to hide.

[Thajocoth]

New cures are always awesome. They just take, like, forever to jump through all the hoops.

Back in High School Biology, the teacher showed us some of those eye tests for red-green colorblindness. One of the students was very confused and asking a lot of questions until he finally realized he's red-green colorblind.

As for seeing ultraviolet and infrared... They mean a little bit into ultraviolet and infrared. You're not gonna see the sun's ultraviolet rays at the beach, or the radio waves in the air... It would basically expand the visible spectrum slightly in either direction.

http://www.equiworld.net/uk/horsecare/alternativetherapies/lighttherapy/spectrum.JPG
(X-Rays, Gamma Rays and beyond are also part of the category "ultraviolet", as the term simply means that it's "more than violet") Similarly, Microwaves and Radio Waves are part of "infrared" as it simply means "below red".

If we expanded our visible light range a little, we'd come up with new names for the new colors.

Also, Serpy, I see turtles in those circles. Otherwise, the first one's Cornell red, the second one's prescription-bottle orange, and the last one is a green you never see anywhere in nature. Also a turtle.
EDIT: But you can't get computer screens to output UV light...

[Serpentine]

Hehee. Okay, you're not a tetrachromat :smalltongue:

[charl]

ME TOO. Haven't met any other music-color synesthetes.

It's not only music mind you. Any sound will do it. And smells too, actually. The only other synaesthete I ever met was a guy who also smelled colours. We had some fun conversations, but it turned out our perceptions of the colour of smells didn't always match up.

[blackfox]

Music produces the strongest colors for me, I guess because it's usually consistent in pitch in a way that screeching tires is not. I do have (projected) shapes and locations for all sounds, though. Also colors for personalities and numbers/letters, numbers being much stronger.

I have the same for the numbers/letters and personalities, though personalities are stronger for me.

[Lupy]

This sounds so cool! So from what I gather you see different letters in different colors projected over the real one and see different colors for different sounds? :smallconfused:

No, I don't see colours. Text is still the same colour as ordinary, like the text is black here. It's just that words and stuff have colours. It's outside my visual sense. I don't know how to explain it better than that. It's just there.

[The Vorpal Tribble]

I've always wondered if I don't have a touch of that... except I don't really 'see' anything per se.

I listen to music and I experience stories. Literally, I love some music solely because of the ideas they put into my head. Or is that just an overactive imagination?

[blackfox]

I have the same for the numbers/letters and personalities, though personalities are stronger for me.Haha, the personalities are stronger for me too. :smallbiggrin:

Also, Lupy, it's less like actual physical sight and more like association or daydreams... although neither of those are really right either. It's like, the colors are in my head, they're not out by the actual music.

[PJ the Epic]

Do you see anything in this?

http://www.blogadilla.com/wp-content/uploads/2008/06/tetrachromat-color-test.jpg

Actually, yes.

The outer egdes of all the circles are a darker shade than the inside/middles of all the circles. It also appears to be more prominent in the red circles

[Mando Knight]

Actually, yes.

The outer egdes of all the circles are a darker shade than the inside/middles of all the circles. It also appears to be more prominent in the red circles

That's because of the decay from the image being encoded in the JPEG format.

[Serpentine]

You mean the individual little dots? I can see that too <.< I think it's like the normal colour tests, there's letters hidden in them.

[PJ the Epic]

Ohh.

I got nothing then.

[Crispy Dave]

All I have to say is that real men are colorblind.

Oh. Would you say it's a good thing though?

[blackfox]

Oh. Would you say it's a good thing though?It's a normal thing for me, having lived with it since forever...

[charl]

It's a normal thing for me, having lived with it since forever...

Word.

It does seem to make it somewhat easier to distinguish between things occasionally. (Oh, you mean that purple guy.) Or you know, so it seems.

[chrissuperman]

All I have to say is that real men are colorblind.

Agreed! I'm not sure how I feel about this "cure." It would be interesting to see how the rest of you "normal" people see things. Like the color orange. I don't believe it exists. I think it's just green pulling a fast one over everyone :smallamused:

I find it helps me remember things, especially names. If I can remember what colour someone's name is, I can usually work out which letter it begins with. For example, any names beginning with J are red. Names beginning with M or E are blue.
