I have been diagnosed as red/green colour blind, have taken the test which confirms this. I find this weird because I don't see myself as colour blind, I feel I can see brown and green, so I don't really understand. I have a problem with colours other than primary colours and don't know the difference.

I took this because although i can pass these tests 100% i still have intermittent colourblindness which seems to confuse blue/green,my doctor thinks i'm making this up and therfore i find help difficult to get any help.

If I had only passed the 1st test, what kind of color blindness do I have? Is there really no way to correct this difficulty with colors? Thanks, now I'm reminded that I am colorblind...cheers!!!

I knew someone who is also a color blind, after he undergo a
colorblind therapy for only 4 days, he claimed he can read and had passed the Ishihara test. Is it possible?

I'm no expert but I never heard of a cure for colorblindness or the idea of "colorblind therapy".

I got only the first one right (16.67% on the test). I knew I was color blind at the age of 12. But never knew that it is so severe. I know that is no cure for color blindness. Wish there are some glasses designed to get 100% on the test. Cheers...

Back in Third Grade I thought grass looked red -- it still does! I'm a writer (investment education)and would like to write a book about my life expereiences (interesting/funny) as a colorblind person. Do you have any stories to share? If so, send to PO Box 4929, Eagle, CO 81631

I didn't know I was color blind until I was playing baseball in a practice field where they spray painted where the bases should of been in a bright pink. I could see it but it didn't stick out. I had to look hard for it. Later on driving confirmed it with having trouble with light colors. Now of coure I know the order and am fine. I find I have good days and bad days with it. I don't ever have normal vision but somedays it is easier to distinguish colors than others. Anyone else have that? Maybe kind of what George is talking about but his is less severe?

[at]George, I have also sometimes hard to distinguish Green/Blue.

I passed colour tests in school, even tought I had really hard time for some variants.

I have really hard time to see anything for the second test here at TJs, as first it just looks like random "lines" in the dots. Then if I look really hard i can barley see the number 6.

Tip: If you have Ubuntu, with properly setup graphicscard drivers ( it asks you to "activate" it at first boot-up ) you can Just press Super+M or Super+N to activate colourfiltering, it can help out a lot, especially if you're tired and some mofo uses a wierd coloursheme at their site. ( Super is the key which can look like a penguin, fish or flag )

I took the Ishihara test 42 years ago and the finding was "red-green viewing deficiency." According to the Wikipedia article on colorblindness, this is now called "anomolous trichomacy" or Deuteranomaly, the latter used to refer to having weak green color discrimination. It's true, as the article says, that dark green appears black in low light, but then so does any dark color if the light's low enough. As a practical matter, it makes no difference on a day-to-day basis and, when I am merely considering colors, I never make any mistakes in color identification. Furthermore, when viewing example pictures which try to show what color-blindness looks like, I always identify with the examples given for normal color vision. As the article elsewhere says, the main problem is in passing color blindness tests! That, and answering the questions of those who want to know "what it's like" to have colorblindness, which I think would be unanswerable even if I were functionally colorblind instead of having an imperceptibly minor color perception anomaly.

I didn't know I was color blind until age 18 when I tried to enlist into the military. I failed the color blind test. They even humored me and let me take it 3 times, because I thought I just had slow visual perception and 3 seconds is not long enough for me to figure it out. It's like I had to prove it to myself. Needless to say I failed all 3 attempts. I couldn't get the job I wanted (Electronic Technician), so I bailed out and didn't go into the military. It's confirmed I am color blind, but The funny thing is that nobody believes me. I can't see deep dark reds, greens, and blues (they look black). On the other end of the spectrum I see white where others can pick out what color is actually in it. I hate websites with faint pastel pink fonts (nearly transparent), and I usually just do a copy and paste to notepad so I can read it. Fully saturated reds, greens, and yellows pierce my eyes, so that's another hated mix. And to this day I still have no idea what Midnight-Navy-Blue is suppose to look like. Individual primary colors are no problem, but when you mix them to either end of the scale I just can't identify them since I'm not getting all of the information. If you put dirty orange and light brown side by side, I'll just pretend I know the same difference as you, unless you ask me to pick the correct one up. If I get it wrong, I'm like "Oh, my bad, I wasn't paying attention to what I was grabbing.", or some lame excuse... LOL. But if you darken the brown and lighten the orange, there's no problem. So obviously I have a few issues somewhere midways in the spectrum as well. I had one doctor to tell me I'm slightly protanopic in my right eye, but mostly deuteranopic in both eyes with my left eye being the dominant one. Now, add nearsighted laziness to my right eye and farsightedness to my left eye. Then add astigmatism, diabetic retinopathy, and macular edema, and I think you can get the picture I'm naturally challenged and my wallet is screaming bloody murder. The good news is I'm 40 and coping with it all and can still manage to get around pretty well (can't drive anymore though). The best news is... I'm not blind... errr, yet.

There is no cure for being color blind. i first found out i was color blind by watching little miss sunshine. it turns out the kid was color blind. i found out i was color blind 2. so i went online 2 take the ishmari test or something like that and i failed. i brought it over 2 my grandma"s and she thought i was lying 2 her. than i got mad and left. and by the way u can only get it from ur mom if she carries it

Hi, i passed it for once but i have some difficulties in finding 45 in last one.what is this mean

Nice!!! the humorous way you put ur story. I am color blind too (red green) and it really isn't as much of a problem as normal people may think. Life carries on quite easily though it put paid to my hopes of ever being a fighter pilot.

I found out I was color blind when I took my physical to join the army. So, I had to be a helicopter mechanic instead of a helicopter pilot. To give you an example of the difficulties involved, when you take a military green helicopter and drop it down below tree level the helicopter basically blends in with the trees and I can't see it. This is true in other colors also. The colors run together and I can't distinguish figures. Just like in the color blind test they give you were you are suppose to see numbers in a group of colored circles, the number just blend in with the cirlces and I can't see them. All I see is a circle with a bunch of colored polka dots in it.
