lol skill issue, fucking noobs!
The shrimp are holier than we are because they cannot see the devil’s color (it’s pink 🩷)
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?
Because white light from an LED bulb is not all spectrums of light. It’s 3. It’s pure red, pure green, and pure blue that stimulates our cones equally so our brain can’t tell the difference. Like how TVs can make any color out of just three colors of sub pixel.
White light from an incandescent bulb is all spectrums of light. Through a prism it makes a rainbow. White LEDs through a prism make three stripes. For more information of this and some visuals check out this article. https://en.wikipedia.org/wiki/Color_rendering_index
I think this speaks to a significant misunderstanding that most people hold of the way vision actually works.
Most people imagine that vision is a relatively simple process by which our eyes detect and transmit to us the nature of the world. Not so.
Eyes are complex and interesting organs in their own right but fundamentally what they do is relatively simple. They are able to detect and report to the brain certain qualities of the light that hits them. Primarily these are: intensity, direction, and proximity to three points on the frequency spectrum (what we perceive as red, green, and blue). But this data alone is not vision. Vision is a conscious experience our brains create by interpreting and processing this data into the visual field before us—basically, a full scale 3D model of the world in front of us, including the blended information on reflection and emission that color entails.
Quite amazing! Most of this takes place in the human brain, and not the eyes. From this perspective, it is not terribly surprising that an organism with more complex eyes but a much simpler brain might have worse vision than we do.
Ha! I read the following Science new article just today about how Purple Only Exists In Our Brains. It’s written for a younger audience (I think), but it lays out how our sight works, and how our brains trick us into seeing purple (a red-blue colour, as opposed to violet).
Poor shrimpos, no purple for them, I bet.
This phrasing always bothers me a little, because, as even the article quotes a scientist saying: “All colors are made up by the brain.”
Purple is special because it triggers from non-continuous wavelengths of light, not because the subjective experience of purple is an invention of the brain. Being ‘invented’ is something common to all colors. Or sounds. Or tastes.

the brain’s actually trying to understand what things are made of, and it’s guessing at that based on the light that enteres the eye.
this is why when you pick up a thing outside and take it inside, it doesnt change color (edge cases exist), even though the light that reflects off of it into your eye absolutely changes a lot.
Reminds me a little of CD digital audio. The original Red Book audio standard hasn’t really been improved upon because it’s uncompressed audio which covers basically all of the range of human hearing within the capabilities of any speaker we could build. It’s uncompressed because in the early 80’s when the tech hit the market, it was completely unfeasible to include the CPU and RAM needed to decompress audio in real time.
Shrimp has more color receptors because he doesn’t have enough neurons to run trichromacy, so he sees in EGA.

love this. nice job :)
I remember experiencing the EGA to VGA graphics evolution when I was growing up. I remember thinking the VGA almost seemed too real.
In my mind, this was a game that felt like it was pretend:
But this felt entirely too real:
Have you played The Crimson Diamond? EGA is back, baby!
If you love the old murder mystery games like the Laura Bow Mystery Series, you will enjoy this game
Oh man, I had completely forgotten about the old Laura Bow games! Might have to check this out!
The way mantis shrimp see is nonetheless super cool and interesting. They likely have no conception of 2D color at all, and can only sense the 12 different colors in general. Furthermore, only the midband of their eyes see color, when the eyes are moving and scanning for prey, they don’t see color at all, which probably helps offload mental load for their small brains. Once they do see something, they then stop moving their eyes to determine the color of what they’re looking at.
Also, mantis shrimp have 6 more photoreceptors in addition to the 12 colored ones, to detect polarized light. They likely see them the same way that they see color, so they probably don’t consider them anything different than wavelength which is what we interpret as color.
Ed Yong’s An Immense World has a section on this and I’d highly recommend it. The ways animals sense and perceive the world are often so different for ours and it’s so fascinating.
