your color vision!
The test below, based on the Ishihara plates, is designed to give a quick assessment of color vision, and should not replace evaluation by a professional!
The original card version of Ishihara's color test was designed to be carried out in a room adequately lit by daylight. This electronic version may produce some discrepancies in the result as the images have been optimised for web-based delivery and with a 256 color display or greater. The results of this test are not to be considered a valid medical test for CVD and merely serve to illustrate the tests available.
