I was once sat in a lecture about various wavelengths of light, and the lecturer went on a tangent about colourblindness. He put up two images side by side and said "this is what a normal person sees, this is what someone with deuteranopia sees", and I'm sat there thinking "this guy just put up the same image twice."
Anyway, that's how I learnt I'm colourblind.

Also, humans can see more colors than any computer display can reproduce.

I know this is a joke, and it’s funny, but I’d be truly interested in a graph that reduces the “what we see” by a ratio equivalent to the difference between what we see and what they see. Do we know enough about the mechanism to even estimate that?

yes, very accurately actually.
For example the internet's favorite googly eyes, the mantis shrimps, have very poor discreet color separation, and also are lacking when it comes to vision clarity, but their eye structure permits them to see both linear and circular polarized light, which is perfect to cut through the camouflage of marine pray and predators.
Also humans have one of the most advanced daytime vision system in the animal kingdom, we are only overtaken by raptor birds and some parrots.

I don't understand shit from these graphs and I always considered myself pretty smart, goddamn it :<

The light we can see is basically the light that gets through water. Water absorbs infrared really fast (a few meters and it's gone), and UV doesn't go deep either, so the band that actually travels is roughly the 400 to 700 nm window, with blue-green going the furthest. Our ancestors' eyes evolved in that environment, and we mostly kept the same spectrum when we came out onto land. So a lot of what we call the visible spectrum is just what was useful when we were fish.

You can't understand something that uses terms you're not familiar with, no matter how smart you ware. First you gotta learn what all the jargon means

the target audience of the post are butterflies, pigeons, goldfish and mantis shrimps... the bottom colorwheel is actually edited and it only show the colors humans can see

Many animals perceptions are in different dimensions as they have access to ours and beyond. I don't know why you're talking shit.
I'm fucking stupid. I'm keeping my comment though. I get it now.

This would see these images as the same because our monitors are not adjusted to displays colors that we can't see

Same colors, different brain.
Color is a wave of heat that your brain interpret.
Same wave for us can be blue, while it can be green for other animals

Since you are human, you don't see the extra printed colors.

We should make it a rule on reddit that people with the same avatar can't respond to one another because it looks like you're talking to yourself.

It’s the same for us because we can’t see the colors they see. Also took me a minute to get it.
