HRR COLOR BLIND TEST

You have to recognize shapes (◯ - circle, X, △▽◁▷ - triangle that can point in 4 directions) that can be placed in 4 positions (bottom, top, right or left side) on the plates. There will be 12 plates. Don't guess. If you don't see the shapes, just select "nothing".

Example: There is an 'X' in the upper right position, and a '◯ - circle' in the lower left.

Please note that online color blindness tests do not give the same results as the original tests. Digital displays have only three primary colors. The colors of the printed books cannot be simulated by a display. 

Not suitable for clinical diagnosis!
