There's some evidence that tetrachromacy already exists in a few humans. If so we have the gene already. But why would it spread?

fringe theory just for a bit of fun: since screen use 3 colors diodes, maybe people with tetrachromacy would be less addicted to screens, making them both more grounded in real life and marginally more successful, leading to them having more children?

I have no idea how to test it. But in my heart I know that screens with RG, GB or RB color models would suck enough that any screen addiction would be cured instantly.

I wouldn’t be so sure, for a decade all we had was G and we used more and more of it until we died of dysentery outside Eagle River.

You were supposed to ford the river!

You know our supplies were:

1 axle.

1 wheel.

1 bundle.

100 boxes of ammo.

10,000lbs of bear meat.

2lbs of squirrel meat.

We sank like a rock.

They need special screens with four colors and the internet updated to make it more interesting for the tetrachromatic.

this is true of many human mutations with the development of medical care, its not like we face evolutionary pressure for many things
