This is worse than when I found out the blobfish is just a normal-ass fish that usually lives under lots of water pressure and had just inflated from the lack of it.

but then they can still set colors, that we don't. Or at least there are some colors they can differentiate between, that we can't.

e.g if they have a receptor for orange, yellow and red, then can differentiate between pure orange and orange that is 50% red and 50% yellow.

So both is true: We have more colors (because of brain-things), but they still have some colors, that we don't (because of receptors).

Can you give any source for this? The text includes 2 key links and the screenshot obviously misses out on them

Top tier science meme!

They still have pew pew claws

So its like they're living compressed png world chosing 4bit as color depth (it's 16 colors tho). I'm no retro gamer but some old graphics presents unbelievable level of expression with limited colors, so it's possible they're seeing something amazing still.

To be fair, we don't see like reverse engineered printing. Printing is reverse engineered seeing. If we saw like this post is claiming shrimp see, and blue was blue and green was green and yellow was yellow, we wouldn't be able to print by mixing three colours. We'd need one pigment per photoreceptor, same as we do now.

I remembered awhile ago hearing that compound eyes can see quite remarkably due to their properties, but if this is true than it's possible that insects really do literally see multiple copies of the world out of each segment since they wouldn't be able to average them out across a spectrum.

This is now our mission. It's the job of science to give these unfortunate creatures the ability to see all the colours. Get on it, molecular biologists.

This means that when they invent TV they will need 9 more colors in addition to RGB.

Can someone explain to me why the mistake made about shrimp is different than the assumptions that went into speculating how other creatures perceive the world? Dogs, bees etc.

I've always wondered what it would look like to be able to see outside the visible light spectrum

Like would it change the colors we can already perceive or would it turn making popcorn into the trippiest shit imaginable, or would it be like Lex Luthor in all-star superman and we suddenly are able to invent new genetic material or some crazy shit.

dafuq you mean fake colours, is white also fake then?

Is there at least a new contender for their place?
