yes you are rite Gradin about the color produced, but the main point is we need to match the color. if the color does not show as the proper color it doesnt matter.

Hi,
I think you have overlooked a simple fact: most people’s computer screens do not show proper colors, since they haven’t been properly calibrated. This would probably affect the test.

Thank you for this test – folk have told me I have a problem with my colour vision and I have seen the Ishihara tests yet I do see quite subtle colours.

When I did your test, though, I found it really easy to match all of the colour squares <> so those folk are right. I’ll be interested to know eventually whether my weakness is in the red or in the green. I found at school the teacher writing on a blackboard in red chalk was impossible so I suspect redis my problem though I still believe I know red when I see it.

Thank you again.
