Technically, all the colors are fake. They're just the halucinations of a brain trying to understand the input from sensory organs.
No, colors are real. And you see them.
Pink isn't real. There is no wavelength of light that is pink.
That doesn't make them fake, in the same way that x can mean 2. You are merely representing a given value (in this case light within a certain electromagnetic spectrum) in a useful way.
I hadn't thought about it that way.
But is my red the same as your red? Hmmm?
if two people can both point to red and agree that it's red, that's close enough. anything beyond that is just pointless esoteric debate.
I disagree that it's pointless. I think it may be beneficial to humanity (eventually) to establish whether or not there is an objective reality which we all experience.
i agree, but that's a job for neuroscience, quantum mechanics, and psychology; not a pack of dorks on the fediverse.
But I want to contribute to humanity in a meaningful way!
-me, a dork on the Fediverse nearly incapable of contributing to humanity in a meaninful way
buy guns
Working on it.
It was a joke?
hahaha?
I hate that it invalidates this episode of radiolab, which is, without a doubt, a masterpiece of podcasting:

i saved the video at the 13 minute mark where they do the audio representation of the vivid colors. still worth a watch/listen
But compared with human eyesight, they could still see more 'colors' - As we see (almost) the same white in incandescent bulbs as LEDs and fluorescents, they might actually see the component colors and their intensities.
Not unlike how we may hear a combination tone when multiple other tones are played, and hear the difference (or sum) of them.
How would you suggest they do that. White light near equally activates our 3 cones because all spectrums of light are in it.
White light near equally activates all 12 shrimp cones because all spectrums of light are in it.
Which spectrum of color is left out of white light that wouldn't light up a cone associated with it?
6500k vs 5000k is noticeable for humans
I need to use wherewithal more in my daily life
Every lunar month, when there is a full moon, i try quitting caffeine

(I initially misread you comment)
I wish I had the wherewithal to use it more often.
My whole world is crumbling
How did they test if they could see color? Did they make little shrimp dioramas or something?
They asked them politely
The easiest way is to use the principles of conditioning. Pair a stimulus with a certain color light, then start flashing up different colored lights. If the organism is cued to the stimulus by multiple colors of lights, it means that they can't really distinguish between them.
That's how we tested when kids lose the ability to distinguish certain phonemes.
it makes me happy when people understand science.

The shrimp are holier than we are because they cannot see the devil's color (it's pink 🩷)
You mean light red?
That is clearly embarrassed white
Disappointed. But didn't the have receptors for differently polarized light? What about that?
Polarization filters on retinal photoreceptor won't make light wavelength (color) be perceived different, it just changes the conditions in which it's detected. If those polarized cells would cover unique colors compared to the rest, it would kinda resemble the highlight effect in Mirror's Edge, where something with a different angle than the surroundings stand out (sudden color gradient)
Color me appointed, at least we're not missing out on fresh new colors!
