It sounds like you have red-green color blindness. What result do you get when you take this test?
I also did the Farnsworth-Munsell 100 hue discrimination test, got a score of 28 on that - ideal being 0, and above 4 meaning something is amiss. So I don't really know what to make of this lol
Now either we both fluked it the first few times or these tests are genuinely not trustworthy. I find that pretty unlikely, but what I do think I know is that I do not have CVD after all.
This one seems to have worked for me: https://www.xrite.com/hue-test
