Many people are looking for a possibility to test their color vision on the web. Unfortunately there arent many color blindness tests available online. So this page shall bring together a series of tests to check your personal type of color vision deficiency and the severity of it.

Please be aware that your personal computer display settings, ambient light and other factors can affect your test result. If you want to get an accurate diagnosis of your color vision deficiency, please visit your local eye specialist.

The often called Ishihara plates were introduced by Dr. Shinobu Ishihara from Japan long time ago. Since then this test is the most well known all around the world.

This test consists of 38 different pseudoisochromatic plates. Each of them hides a number or line behind colorful dots. Based on what you can see and what not, it is possible to check if you are suffering from some form of red-green color blindness.

As the test is usually executed in a booklet, it is not the best possibility to online test your type and severity of color blindness. Other tests like the arrangement tests below show better results.

This famous color vision testwhich is based on 88 colored plates and not 100 as the name suggestwas introduced in 1943 by Farnsworth.

The test will show you four batches of 22 mixed colored plates. What you have to do is to arrange the for rows of plates in a correct order. Thats all.

All misplacements will be summed up to your personal total error score. The higher your TES is, the more severely colorblind you are. On the other hand you can also get some information on the type of your color vision deficiency based on the area around your biggest error points.

In 1947 Farnsworth released the D-15 dichotomous test. This is to this day one of the most famous color vision deficiency test and definitely the most famous color arrangement test.

You simply have to arrange the given colors in the correct order of colors. If you are suffering from some form of color blindness, you will arrange them quite differently compared to persons with normal color vision.

With this test is not only possible to check the type of your color vision deficiency but also its severity. Unfortunately the test results are not completely reliable, which is a base problem for all types of online color vision tests. But the result will be a good indicator of your correct color vision abilities, specially if you take it under different conditions.

This is my first try to develop a simple red-green color blindness test. It is based on the idea of the real anomaloscope, made from two different light sources which have to be brought to a match.

Just match the left color to the right one using the slider below the box. If you can match several of them you are definitely red-green colorblind. Originally I wanted to retrieve more detailed information from the test results. But it didnt work outyet.
