The original Ishihara color blindness test was introduced in early last century and since then, it is by far the most well known color vision deficiency test all around the world. Dr. Shinobu Ishihara from Japan produced three different test sets which are widely used and which all based on the same pseudoisochromatic plates. This test is actually designed to be used in a booklet and is usually executed by an eye doctor.But I have made an onlince version of the test, available right here. The online test is based on the 24 plates edition and will give you a little feedback at the end of the test. As this test is only made to check for red-green color blindness, any other form of CVD can not be detected.

"The Ishihara Color Blindness test - named after a Japanese Professor at the University of Tokyo - is the most well known tool to test for red-green color blindness. Mr Ishihara developed this test almost 100 years ago. It was first published in 1917 and is used since then to check if someone is suffering from protanopia or deuteranopia, the two different kinds of red-green color vision deficiencies. A collection of 38 plates filled with colored dots build the base of this test. The dots are colored in different shades of a color and a number or a line is hidden inside with different shades of an other color. But enough theory, take the color blindness test by Mr Ishihara yourself and be surprised (or not) of the result."--Www.colblindor.com/2006/03/15/color-blindness-test-by-dr-shinobu-ishihara
