They reside in the X chromosome and sometimes one is defective or missing. That’s why color blindness is more common in males.

Yeah. That’s a little out of date.

Colorblindness isn’t worse vision, just different.

You got more rods for the missing cones, it’s not just blank space.

That helps lowlight vision, and the colorblind are also better at differentiating shades of brown.

Like, my dad was colorblind, and he could spot a deer in the woods from like a mile away. To him it was completely obvious and he never got why other people couldn’t see the deer.
