Is a planet with a sun that renders everything black and white possible, scientifically? I heard people talking about infrared n shit.
>>16142520you can't have monochrome white light. (white is a human brain construct)
>>16142520No kiddo, that is not possible. Dune is more high fantasy than science fiction. It even had an OP magical little girl but the director chickened out and instead we got a fetus.

Different stars, different light and physics.

>>16142559I think he's calling you his older sister?
>>16142563>I think he's calling you his older sister?I thought he was calling me nigga but autocorrect fucked him
>>16142562not for humans. need to fuck with the brain/eyes
>>16142566>not for humans. need to fuck with the brain/eyesWhat has to be the case for Harkonen eyes to see only black and white in the sun?
>>16142570https://en.wikipedia.org/wiki/Achromatopsia
>>16142575the shade has colour though in the movie and it only becomes black and white when the sun is shining, what would cause this?
White is a combination of colours. Brown and black are not.
>>16142580brown light is just dim orange
>>16142576we have an iris which closes with more light. so they'd need to have some different mechanism of dealing with high intensity light, such that when it kicks in it goes black and white because reasons
>>16142545That was some quality dank meme.
>>16142591>such that when it kicks in it goes black and white because reasonssuch as?
>>16142611>That was some quality dank meme.yes
>>16142520That isn't Dune, that's Geidi Prime, and it's meant to be unnatural on purpose.
>>16143737*Giedi
>>16143711fuck would I know
>>16142576It isn't shade vs. sun. It's Dune vs the Harkonnen planet.
>>16143711could also be some heavy UV light after their star rises in the sky. and their eyes switch to UV detector cells.https://www.youtube.com/watch?v=V9K6gjR07Po
>>16143737I mean dune as in the franchise, obv the planet isn't arrakis
>>16142566It literally happens with moonlight.
>>16143752give some possibilities, elaborate further n shit
>>16142523all light is "monochrome", electromagnetic waves don't have colour
>>16143766yeah I tried here >>16143762
>>16142520It has more to do with the cone cells inside your eyes. Seeing black and white, regardless of the illuminating light spectrum, would be possible if we had one type of cell cone that is only capable of detecting the presence of light from its absence. If they happen to be sensitive to light intensity, our brain would be able to process shades too.
>>16142550It has terrible file size limitations and webm is a goyslop format, my negro.
>>16142550/sci/ doesn't support audio in webms, that video has audio in it.
>>16142524This. Dune is literally a live action anime.
in case the sand worms didn't clue you in, Dune is not a staple for scientific accuracy
>>16143762>>16143770based, thanks for responding but can you elaborate more? I appreciate your response
>>16143865looking into Achromatopsia it seems that they have fucked color cones, can detect only blue or red or something like that. but if the Dune dudes can see color in low light, then they must have inverted cone/rod function/activity.photopic vision uses all three types of cones in bright light.mesopic vision uses all cones and rods in low light, like night time with some lights and stuffscotopic vision which uses the rods only, for very very low lightso they might use the rods for high intensity light, and be monochromatic, and and lower intensity light they switch to cones and color.I know jack shit about it but for sci-fi it could pass as some mutation.
or have two of the three cones fucked somehow, genetically, such that past certain light level they crap out and don't send any info to brain, so they see through one type of cones past certain light intensity. and brain just removes that cone's color from representation, replaces it with gray. and this could be due to some light wavelength bias, like way more blue light, or red light. or green. whatever the cone color that still works past certain intensity.blue or red stars exist but are there (predominantly) green light stars?if you want it to make sense somehow you can consider humans going there and in time loosing two of the three cones during daytime since they're not as useful
and if their star is blue and you maybe make the planet larger but lower density to keep the 1G, you get more atmosphere between you and star, so more blue light gets filtered, thus making at sunset for a somewhat Earth daytime color spectrum, hence why they see like us in low light. but have no idea on the math if it works out.
>>16143990>you get more atmosphere between you and starat sunset
>>16143774The people in Dune are people.
>Rauta HärkönenYou should really visit Finland during late autumns and you would know it's true in this planet
>>16142520i... i kinda want to fuck his rotten psychopath mouth
>>16143913>so they might use the rods for high intensity light, and be monochromatic, and and lower intensity light they switch to cones and color.makes sense, why would they have this mutation though? what evolutionary reason could there theoretically be?
>>16144151>i... i kinda want to fuck his rotten psychopath mouthsame
>>16144154see >>16143953 and >>16143990
>>16142520ralistically, a planet like Arrakis would be uninhabitable, let alone by a giant worm.for the simple reason that there is not enough (if any) food or water.such massive creature would require gigantic amont of both
>>16144174does it feed on spice?
>>16144184isn't spice supposed to be worm shit?
>>16144198dunno, but they get that blue Water of Life from their guts so that's like their blood or something.
>>16142524She grew up to be MILFy.https://www.youtube.com/watch?v=TuiJmUw69Sc
>>16144156that makes two of us. can't help it, the way he tongued the blade was simply hawt.
I'd impregnate this alien freak
>>16143768Yeah, but white light would mean no atmosphere.
>>16144346huh?
>>16144453Atmospheres scatter light. It's why the sun looks yellow from earth.
>>16142520Colour is something the mind creates from sense data, not something that exists in the photons.
>>16144504It can easily be done through mass hypnosis, then.
>>16144489Colours do not physically exist out there in nature or the clouds or the sun. No photon has colour as an attribute, not when it is emitted from the sun nor when it is scattered by the clouds. Colours only exist phenomenally in the mind. The mind creates colour by arbitrarily assigning three different wavelength sensitivity bands via three different types of cone cells in the eye to three different phenomenal colours. If there were only one type of cone cell, with only one sensitivity band, then the mind would only see one colour: which is how we see with our separate rod cells in low light conditions.
>>16144518Okay? The atmosphere scatters the sun's white light so we perceive it as yellow. Didn't say otherwise.
>>16144545there is blue light making it down to Earth. at sunset there's more air between you and the Sun so more blue gets filtered.
>>16144560Yep.
>>16144545Trichromatism is not essential to humanity, nor to hypothetical beings in a fictional universe. They will see the colours their minds produce, atmosphere or no atmosphere. The colour is in the mind, not the clouds or sky or sun.
>>16144518Are you the guy that keeps turning every conversation into how light is just a hallucination of mind? It's not profound dude, did you just figure out our brain interprets physical stimuli?Do you rush into a movie and scream about it's only photons eliciting a chemical response in the brain? lol jesus....
>>>/lit/23314259
>>16144560That pic is bullshit, evenings are blue with clear weather. Moonlight and starlight are very similar to sunlight, only dimmer.
>>16144568They are all meant to be people, the movie is just so shitty.
>>16142520No. If there is visible light there will be color. If there is no visible light there will be no color, but it will also be completely dark.>>16142553That's not how light or physics works.
>>16144198No it's jizz
>>16142520Giedi Prime in the movie clearly had a weird atmospheric deal going on. The ink-blot fireworks looked like they were crashing up against some kind of surface.Might be an artificial planetwide field that filters out all but a narrow band/bands of light for habitability reasons.
>>16142520Yes, monochromatic light exists, and it is freaky. Easyest-cheapest method has been sodium Sulphur, don't know if there are some newer led based approaches. Don't expect a start to do this. And it's not actually black and white, but it's close enough that the distinction does not matter.
>>16142520>a sun that renders everything black and white possiblenot black and white, but you could, hypothetically, have an atmosphere that would permit only certain frequencies of light to penetrate it.While black-and-white isn't possible, a monochrome effect is, as in what happens on earth during a sandstorm, everything turns orange-brownish, depending on what type of dust is in the air.

>>16144892>Yes, monochromatic light exists, and it is freaky. Easyest-cheapest method has been sodium Sulphuranon didn't yet learn about fucking LEDs or handheld lasers.
>>16144901yes every gamer knows "monochromatic" light
>>16143763imprecise language makes you look like a low IQ homosexual. Be specific. "Dune planet" implies Arrakis. Arrakis = Dune. In a story about vast interstellar empires maybe you shouldn't lump all the world's into one generic phrase and expect a valid response.
>>16144895that doesn't explain why they can see color in lower light conditions.
>>16142523>then how come the movie depicts monochrome white light???
>>16145341their brain interprets it as white. human eyes-brain combo can't, if healthy. so there must be an issue with their eyes-brain system.
>>16143763Then don't call it "THE Dune planet." There is a main planet in Dune that one could call THE Dune planet, and it's not Giedi Prime. If you didn't remember that name or want to look it up, you could have gone with "the Harkonnen planet from Dune" or even just "the bad guy planet from Dune" and you would have looked less stupid than calling it "the Dune planet."
>>16143768Then how could it be monochrome?
>>16145997it can't. unless you point to a monochrome star.
>>16144895>While black-and-white isn't possiblefr why tho? it looks so cool
>>16145300>>16145465tdlr no bitches and you're a retarded nagger
>>16146177holy fucking shit it's been answered a ton of times already what the fuck
>>16146177Monochrome effects work because items reflect differing amounts of the respective color's light. So a blue object lit with blue light will be brighter than a purple object, which will be brighter than a red object (which would just look black).But white isn't a color (or more precisely, it does not have a distinct wavelength). It's a combination of every color and so every item will reflect all the light that it can, which then just creates a normally lit environment.
>>16142520No its not
>>16142523All perceived color is a brain construct. Monochrome is monochrome if you can see the spectrum.
>>16145997The output signal is the exact same, just varying levels of strength
