Want to take a Color Blindness Test? The Ishihara test (a series of test plates made up of colored dots) was invented by a Japanese man (Dr. Shinobu Ishihara) almost 100 years ago. Let’s get started!
1. Take out a piece of paper
2. number it 1 to 21
3. click on this link –> http://www.colour-blindness.com/colour-blindness-tests/ishihara-colour-test-plates/
4. write down what you see on each plate. For example. you would write down “12” when you see the following plate.
5. When you are done, you can go back and click on each picture to figure out if you are color blind.
I can tell you that on plates 2, 4, 5, and 8 throu 13, I am DEFINITELY in the “red-green” color blind category. the fancy word for red-green color-blindness is “Deuteranopia”
If you want to know what color blind people see, the pictures at this site seem pretty accurate for my Deuteranopia. In most cases, the two plates look the same to me.
