That’s a nice find. I just finished my test there and scored 8. It’s still in the perfect region amongst 20-29 year old males.
But I think the test also depends on what monitor you use and what color schemes is setup.
So there’s a possible error margin I believe.
But one still gets a pretty good idea of how good he can discern colors.

And I wear glasses, too.^^

without glasses for 16-19 males . I have 38 . still some problems with purple and blue for me . need glasses
