Test 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.

Position yourself about 75cm from your monitor so that the color test image (a dotted disc) you are looking at is at eye level; then, select an image, which contains a 1 or 2-digit number, or a shape, and see what you can see!
