but then how would we (non color blinds) all perceive for example blood as red? I'm not saying we perceive it in exactly the same color shade but we all see it as red.
I'm more intrigued by the colors that exist that we do not know

Human eyes are able to percieve UV too. It's the cornea that filters out the UV part of the EM spectrum as long exposure to UV damages the retina. There's this documentary where a guy was able to percieve UV light with one eye after surgery on his cornea. It's shape was altered so it didn't filter out the UV no more. He's description of the way he pecieved world was intriquing to say the least. I think it was in a episode of Richard Hammons Invisible Worlds.

I know we can see into the UV spectrum (I have a UV responsive Tattoo ), but they see deeper into it or more variation where we don't

apparently the Papilio butterflies have 6 cones, and Stomatopods can have up to 12 cones!!!

The midband region of the mantis shrimpâs eye is made up of six rows of specialized ommatidia. Four rows carry 16 differing sorts of photoreceptor pigments, 12 for colour sensitivity, others for colour filtering. The mantis shrimp has such good eyes it can perceive both polarized light, and hyperspectral colour vision.

I work security and the last nightclub I worked at the bar tender and I got into a conversation on this, I have been extremely interested in this topic as the first mushroom trip I had the whole world turned black and white for a while
Any way the bartender I talked to actually used to have to wear goggles like in this most hilarious UCB skit from conan.
He see's color totally different than we do and he had to relearn every color for traffic lights etc.

Same here. I have thought about this since I can remember.
I'm pretty sure most people talk about that question we a few of their friends.
I asked myself that question (again) just 2 weeks ago.
How do others perceive? is it the same way I do? etc

 Its like there is a mental bond between the members of this community. As many already said I've been pondering on that issue since childhood.
The way I see it our perception of light depends on the input receptors i.e. the opsin molecules in their cone cells and the area of the brain that puts this information together.
Quote:
Because humans usually have three kinds of cones with different photopsins, which have different response curves and thus respond to variation in color in different ways, they have trichromatic vision. Being color blind can change this, and there have been reports of people with four or more types of cones, giving them tetrachromatic vision.
Genetic variations alter the absorbance properties of the opsins and the signal interpreration circuits so some people do in fact see colours differently. Some of them probably even ponder on the topic of this thread and never actually find out that they do see colours differently.

The majority of us perceive the same wavelengths. It's just how we agree on naming such results.
As for colorblindness, I'd be pissed if I couldn't see the wavelength we've called green.

ANybody else think that perhaps there are colors we haven't seen yet?
For example: When florescent colors/hot pink etc came out, it was, for all intents and purposes, a new set of colors...???

to him, green is a lie
I worked with a guy that saw brown and pink as the same, he rebuilt and painted steering columns on stolen cars, he had a brown one to do that came out in a lovely shade of pink, after that the office personnel had to start asking the color of the interior so they'd know where not to send him

I read somewhere that asking this question is a common thing for kids at a particular developmental stage, just before the high school years. Many, but not all, kids had this thought. Its a great question to ask.

I've thought about this too. colors make up such a small fraction of the radiation spectrum. I wonder what it would be like to see into the infrared, ultraviolet and beyond regions.

I took a class with a guy that saw red and green the same. The instructor was using colored chalk and he couldn't see the red chalk because the blackboard was green. It must be quite a conundrum to see the prof writing and nothings there!

No you don't actually see the UV radiation with UV tatoos. What you see is the UV light charging the particles in the ink making them emit light in the visible spectrum.
It's really fascinating how limited our visual perception is. Check out the documentary I talked about! The guy who is able to see the UV spectrum is in part2.

Why does this guy refer to his butthole as his 'entry hole'? I'm not sure about you but my asshole ain't no entry. It's exit only.
