Interesting thing about people with deuteranomaly, is that in some situations we can utilize luminance and S-cone data better than most people with normal vision. That's how Ishihara hidden plates work (numbers that are visible only with color vision deficiency). But some normal trichromats can also read these hidden plates: https://jov.arvojournals.org/article.aspx?articleid=2135713
That's not how I read it. Normal trichromats see noise on L/(L+M) axis, for red-green color vision defective that axis is L/(L+L). We use S/(L+M) axis and luminance differences. Some normal trichromats can see through that noise.
To understand how it feels lets compare with a superior vision of birds [1]. "That bird is mostly black", I see what it does not see.
With normal vision colors pop out. I've checked once emulation, animal tongue is so red (displayed as hot pink), the brightest point on the picture. Meanwhile it is "just red" for me.
There have been plenty of times where I (r/g colourblind) have been able to see paint mis-matches on red coloured cars where people with normal vision haven't seen an issue, and I've been able to tell at a distance which panel has been refinished. I think the input/output curve of my red perception is non-linear compared to normal colour vision, and while on a lot of that scale it is a deficiency, in some situations, I have improved sensitivity.
Having said that, I'd trade in a heartbeat, so I could see bloody charging LEDs properly.
