Find out if you have color blindness with this Ishihara test. It is named after Dr. Shinobu Ishihara. The test contains various simple color picture plates with numbers in it. If we see the numbers, then we can completely distinguish the colors.

Before you start the self assessment, adjust the brightness of your screen and stay at about 75cm (29inch) away from it. The graphics from 1 to 17 show numbers. You have to be able to recognize them in no more than 3 seconds. The images from 18 to 24 shows a path that you have to follow from one X to the other.
