Please note that computer based color blindness tests do not give the same results as the original tests. Computer displays have only three primary colors. The colors of specially developed devices cannot be simulated by a display. The test can only determine (modarate and severe) red-green color blindness. Not suitable for clinical diagnosis! The test consists of showing 9 pairs of vertically oriented lights. Combinations of either red, green or yellow. Identify the colors up and down (some of which are identical).The colors are shown for only two seconds. If you can not identify the colors, just click to the next button.
