And red/green color blindness isn't less colors, you get more shades of brown.
Which sounds shitty, but invaluable for hunters.
My dad legitimately didn't know what other people saw for "red" but he could spot a deer in the middle of the woods like it was neon yellow.
I believe the downside to tetracheomacy is less rods because the extra cones are taking up more space. Which I think translates to really bad night vision.
Same with my dad. He said that the military liked red/green colour blindness for spotting camouflaged stuff.
This link is very interesting. Interesting for people that are colorblind, and interesting for people that are not.
I could see 3 out of 4 of them but I'm not colour blind...
