Ishihara Plates Color Blindness Test in a Leaflet
- Posted by Daniel Flück on February 15th, 2007 filed in Tests
Just recently I found this new Web 2.0 application where you can produce your own leaflets. A leaflet is a miniature web site which can be created online and distributed through an URL or an embedding link.
I thought this could be a great way to show the 35 Ishihara plates to test your color blindness. All plates show a big circle consisting of many little colorful circles. Because the circles differ in color and brightness it can get really tough for a colorblind person to see the shown numbers or traces.
If you take the following color blindness test be aware that those pictures were scanned and are now reproduced by your display. This can alter the colors. Because a color blindness test relies solely on correct color reproduction you shouldn’t take the results for granted. If you really want to check your color blindness you should see your local doctor.
Could you perform as you expected? Or did the plates show that you really are red-green colorblind? I hope you could spot at least the number in the first and the trace in the last plate, otherwise you may have a real severe color vision problem…

is any way high myopia can be the reason for red green color deficiency

Good question.
High myopia is never the reason for color blindness. But there can effectively be a relation between the two.
Stay tuned. I hope to cover it soon in a special article on Colblindor.

Daniel, can you please tell me an address with the full Ishihare test as you have it here (33 plates) ?
Thanks.

Vasile, there is only one place I found which shows the whole set of 38 plates. You can find it at Les Daltoniens.

how can i create my own colourblind test for a uni project?
October 22nd, 2007 at 7:41
Arran, it’s not easy at all to create your own test. To create your own plates, which are not readable for certain colorblind people, you will need a lot of time to paint them, or write a computer program which does it for you.
Or otherwise you find your own type of color blindness test. Would be interesting to see your results.

how can i get embedded code for ishirara test?
October 28th, 2007 at 13:05
To embed the above Ishihara color blindness test you have to include the following code into your site.

This test is the biggest load of BS ever. Where would you ever come across something like this in the real world? I can’t be a cop because of this test…and I don’t understand why. People don’t wear clothing that looks like this…cars aren’t painted up like this…there are many more ways outside of color that can be used to describe people and objects. All this test proves is that I can’t see numbers in a circle…nothing more.

Hi
Wanted to ask you whether you know of any Ishihara test generator applet/program.
I’m almost sure I saw it somewhere but I didn’t manage to find it again
Thanks

Ariel TM, unfortunately I’ve never heard and never found such a generator. It would be great to have one. Maybe I’ll release one in the future (when I find the time). And whenever you find one I would be very happy to learn about it.

Jon, check out the article about Secondary Color Vision Tests for Pilot Candidates. This will give you further details about the possibility to become a pilot even with a slight color blindness.

hey, i missed #’s 11, 12, 22-29, 36, and 37, on a scale from 1 to 10, how bad is my deuteranomaly colorblindness?
January 18th, 2008 at 14:30
Max, it’s always hard to give a measurement of ones color blindness, because of different perceptions and different display settings.
Compared to me, you are performing way better. So I would say you either have a mild or moderate form of deuteranomaly.

I am entering the military, I was wondering what edition of the isihara do they use? How many plates are on the test?
January 20th, 2008 at 18:05
Gavin, I have no clue, which type of pseudoisochromatic test they are using. There are a lot of them available. The Ishihara plates are just the best known one besides HRR and others.
Talk to them about your color vision deficieny and don’t try to find a solution to just manage the test.

Daniel I just did the Les Daltoniens test. I got 24 out of 25 with the numbers in the circle. I had no problem seeing the numbers yet the test i did today was so old and faded i could not see the numbers clear yet i know i am colorblind but not much yet i still did not get the job. Someone should take this to court. If i could do something to fix the problem i would I shoudn,t be screwed over because of a genentic defect.And the sorry i don,t make the rules is getting old fast.
March 13th, 2008 at 18:45
Gavin you wont have a problem getting into the milatry as long as you dont want the navey the pipes on the ships are color coded] and the airforce too many different color light in the plane on the ground. Good luck Dave

um wtf? purple line in 36 and 37? i only see redline. What blindness i have? i saw the other just fine
May 19th, 2008 at 7:23
I seem to be a very very slight deutan. In all of these plates i see that different colors exist but occasionally it takes a few seconds to pin down the exact number. The ishihara is the only test where I have any problems, however it is also the most commonly used. So, It really bothers me that this test is so much harder for me than any other.
May 20th, 2008 at 12:28
Yeh same here bizzle, from a distance i can make out the number, but one enlarged i can kinda of see it, but kinda of cant. I can make out the basic shape and outline. And yeah i havnt had too many problems with other color blindness test but no fear, going to optimist on Thursday to see if i can still apply for the police

Where can i buy a special lens for the color blind
June 20th, 2008 at 11:54
Francis, have a look at the article about color lenses. You will find further information there.
