The principle and basis for the Ishihara test chart are the quality of the colours and the colour arrangement. Imitation test and online tests have no scientific basis and are not reliable, resulting in a high rate of false positives and/ or false negatives. We highly recommend you do not use the online version for official purposes. You can buy the original Ishihara test books through this webshop.
