Somewhat? I wonder how you would measure that. Many long years ago a co-worker was explaining a control panel to me. It had red and green LED indicators. He had them backward as he pointed them out. I asked him if he was color-blind. His reply was "Yes, a little bit."

It seems to me that when everything looks the same from birth on (excepting perhaps focus. ;) ) then it is difficult to compare what one sees with what others see.

I also wonder if some colored LEDs tend to be "worst case" as they may be monochromatic and if the eye is not sensitive to that particular wavelength, it will not be visible as color.

Actually... I also wonder about how a wide gamut of colors can be represented by relative intensity of three primary colors: red, green and blue. I would expect the emitters in, for example, an LCD screen to emit light at specific frequencies. How can any combination of three frequencies represent what must be a broad rage of frequencies that form any given color in the world around us.




They use tests like https://www.eyeque.com/color-blind-test/

How colorblind you are -- or maybe in what way -- determines which color combinations you can distinguish characters for. That's horrible, I know, but I'm tired.

I suppose it depends on what mutation(s) you carry. And probably other factors that affect penetrance.


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.
