I think the tests provide an objective measure of color blindness (or maybe better described as color acuity.) I was more interested in the subjective experience. How can someone know what they're missing if they have never experienced it.

Fair enough.

So "somewhat" was the diagnosis, not my experience.

But I have known other red/green colorblind people. And I can distinguish reddish vs greenish colors better than some. But worse than others.

Interesting. I didn't know that red/green color blindness could be partial. In the case I cited, the person was completely unable to distinguish red/green LEDs so I assumed his condition was complete, but perhaps it was just the specific wavelengths involved that were troublesome for him.
