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.
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.
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.
With psychedelics, I saw colors that I'd never seen in reality. But that's just color illusion on steroids.
What interesting, though, is that I saw patterns in objects that normally seemed ~uniform in color. So maybe "software tweaks" can mitigate hardware limitations.
