Take your time looking at each colour plate and try to recognise the most obvious number on the disc. Click on the answer button to compare your result with the right answer.
This computer test may only be used as a rough estimate of your colour vision due to inconsistencies and differences in the coloursettings of computer monitors. Also, it is possible that you can recognise all colour plates shown in this computer test even though you may actually be suffering from a slight colour deficiency. If in doubt, this test should be performed in Prof. Findls private practice with the original set of colour plates.
