6	->''Red skies at night, sailor's delight. Red skies at morning, sailor take warning.''
7	-->-- [[https://en.wikipedia.org/wiki/Red_sky_at_morning A traditional rhyme by mariners,]] and the {{Trope Namer\|s}}
8
9	Clouds are symbolic. White, fluffy ones mean happiness and light. Looming grey ones mean doom, disaster and, more prosaically, bad weather. They're no less ominous in fiction, as evidenced by the tropes AStormIsComing and the ClicheStorm. But what if the sky is red?
10
11	Often the clouds being talked about are more... direct than their symbolic cousins. They're not just a sign or symptom of impending [[TheEndOfTheWorldAsWeKnowIt doom and disaster]], they ''are'' the impending doom and disaster. Maybe they're a mass of enemies so large that they just ''look'' like a cloud, or maybe they're some ghostly beast of a supernatural nature. Maybe they burn. Or maybe they just hang there looking ominous and threatening to unleash something awful, which never happens because the player/watcher either sees the story through to a HappyEnding or [[NightmareFuel turns off the television]]. Or maybe it's nothing more than a visual representation of a story being dark and edgy. Whatever they are, you'd better believe it won't be good.
12
13	Evil clouds are not ''necessarily'' red, but this is still [[GoodColorsEvilColors the general colour of choice]]: Red signifies a hazard in the West, so showing clouds in a crimson hue automatically flags them as dangerous. When the clouds roll red, it's time to run.
14
15	There is some TruthInTelevision to this, namely in the latter half of the "Red skies at night, sailor's delight. Red skies at morning, sailor take warning" adage. This is due to two things: 1. storms usually move from west to east, and 2. the sun sets in the west and rises in the east. In other words, approaching clouds will be illuminated in red in the morning, usually a sign of rainy weather to come. Clouds going away will be illuminated red in the evening, a sign of dry weather.
16
17	Subtrope of PortentOfDoom. See also DeathFromAbove and CosmicFlaw. [[JustForFun/IThoughtItMeant Not to be confused with]] RedEyesTakeWarning though it can elicit a similar reaction. Related to RedSkiesCrossover (when the source of the red skies is someone else's problem). If the sky is supposed to be red, then it's an AlienSky.

24
25	[[folder:Anime & Manga]]
26	* In the anime version of ''Manga/AttackOnTitan'', the sky turns red when [[spoiler:Eren awakens the wall titans and initiates [[ApocalypseHow The Rumbling]].]]
27	* ''Manga/{{Berserk}}'':
28	** Red skies show up several times, usually when Guts or the Hawks have to fight one of the many demons of the series.
29	** As soon as the Crimson Behelit activates, the surrounding skies turn blood-red, immediately preceding [[TotalEclipseOfThePlot the Eclipse.]]
30	* ''Anime/Danganronpa3TheEndOfHopesPeakHighSchool'': In ''Side: Future'', the sky is ''always'' red. [[spoiler:Might be justified, as it takes place AfterTheEnd.]]
31	* ''Anime/DragonBallGT'': When Shenron is summoned, the sky usually turns black. But after the Dragon Balls crack due to too much negative energy accumulated from the wishes in the past, when the Z Fighters attempt to summon Shenron, the sky turns red instead, and an evil dragon appears who splits into the seven Shadow Dragons.
32	* The "Catastrophe" arc of the ''Manga/{{Gantz}}'' features a red sky that heralds the [[spoiler:AlienInvasion]].
33	* ''Manga/HeavensLostProperty'': When [[spoiler:Hiyori]] returns from the dead (more or less) she has been corrupted. When the main cast finds her, the sunny sky turns deep purple as she reveals how much she was changed. Justified, because she was given [[WeatherManipulation weather control powers]].
34	* ''Anime/HellGirl'': The AfterlifeAntechamber where [[TheFerryMan Ai]] and her [[{{Youkai}} minions]] take their targets before ferrying them to Hell proper sometimes has this as a feature. In a few cases, it's the only visual difference between the AfterlifeAntechamber and the world of the living. The perpetual sunset in the realm where Ai resides also becomes this when she offers her [[DealWithTheDevil deal]] to a prospective client. [[spoiler:Michiru also gets a sunset world when she becomes a second Hell Girl, with the same red sky when she meets with clients.]]
35	* Night time in ''Anime/{{Hellsing}}'' seems to always feature red skies.
36	* ''Manga/{{Naruto}}'':
37	** Members of the Akatsuki organization can be identified by their black cloaks with a pattern of red clouds.
38	** The only colors in the Tsukuyomi illusion are black, white, and red. Especially ominous is the red moon when Itatchi tortures Kakashi.
39	* ''Anime/PokemonTheSeriesXY'' has the sky turn red during the fight with Lysandre.
40	* In ''Anime/RebuildOfEvangelion'', [[spoiler:during 2.0 Shinji causes the start of the Third Impact. Guess what the color of the sky is.]]
41	* In ''Manga/RedRiver1995'', Yuuri asked Ramses to have the horse halt to look at the setting sun. She trembled at the eerie blood-red color of the sky and contemplated about the Japanese old saying "Twilight invite devils to rise," feeling anxious about the situation of Kail, Ursula and herself at the moment. Her hunch was right - back at the capital, Ursula was hanged on the background of the very same sunset, around the same time.
42	* In the first episode of ''Anime/SaintSeiyaOmega'', the sky turns red right before [[BigBad Mars]] appears to kidnap [[BigGood Saori]].
43	* Happens in the ''VideoGame/SengokuBasara'' anime whenever we see UsefulNotes/OdaNobunaga's hideout, complete with DramaticThunder.
44	* The sky briefly turns red when Asura is released in the anime adaptation of ''Manga/SoulEater'', and later on when Arachne uses him to increase the spread of insanity throughout the world. Appropriately, the only 'blue sky' left is in the [[BiggerOnTheInside Death Room]]. Once Asura is defeated, the sky immediately returns to normal.
45	%%* Happens in ''Anime/YuGiOh5Ds'' when [[spoiler:Aporia comes into existence.]]
46	* In ''Manga/YuYuHakusho'', when the demon bugs start appearing in Mushiyori ("Swarm" in the dub and "Swarm City" in the manga), the sky turns red.
47
48	[[/folder]]
49
50	[[folder:Asian Animation]]
51	* ''Animation/PleasantGoatAndBigBigWolf'': A variant, in that the sky is purple instead, but it still counts as the sky in the ''Pleasant Goat'' universe is generally not that color. In ''Joys of Seasons'' episode 34, the sky turns purple when the crack it forms from Wolffy being hurled into the sky one too many times finally breaks, creating a big hole that pours out rain and threatens to flood the Green Green Grassland.
52	[[/folder]]
53
54	[[folder:Comic Books]]
55	* In the backstory of ''ComicBook/BlackHammer'', the skies turned red during [[BigBad Anti-God]]'s universe-threatening attack on Spiral City. [[spoiler:When the skies about Spiral City start turning red in the alternate reality created when the heroes left the farm, it's a clear sign to everyone involved that Anti-God is returning to finish what he started.]]
56	* In Franchise/TheDCU, they have red skies, which includes the clouds, whenever there is a major reality-threatening crisis. This was lampshaded in ''Joker: Last Laugh'', when the Joker, during his vast campaign against all of humanity, complained that he didn't warrant having anti-matter waves and red skies. In ''DC Universe'' #0, the prologue to ''ComicBook/FinalCrisis'', this was explained by "the Bleed" (the space between universes and "life-blood" of the Multiverse) seeping through into the material universes due to damage to the structure of the cosmos.
57	* ''ComicBook/{{Hellblazer}}'' once put John Constantine in a twisted nightmare/facet of Hell sort of version of America, with a monotonous dull blood red sky. John is... less than thrilled.
58	* It happened during ''ComicBook/MarvelVersusDC'', too. With the caveat that that time, the sky was red because it was ''literally'' bleeding.
59	* As said by the ''ComicBook/MouseGuard'':
60	-->''Red sky at night, Guard Mouse's Delight. Red sky in morning... Guard Mice take warning.''
61	* In ComicBook/{{Supergirl}} story arc ''ComicBook/ManyHappyReturns'', a red sky was Linda's clue that their time was running out and the original Supergirl had to be sent back to Earth-One at once before TheMultiverse collapsed because Kara didn't fight the Anti-Monitor.
62	[[/folder]]
63
64	[[folder:Fan Works]]
65	* ''Fanfic/AbraxasHrodvitnon'': Monster X's electrical powers and [[spoiler:the partly-resurrected Ghidorah]]'s WeatherManipulation turn the sky into a hellish-looking tempest glowing with red and yellow light.
66	* The sky of the ''[[http://www.tthfanfic.org/Story-14421/spaceman+Halloween+World.htm Halloween World]]'' is permanently and globally red, as well as being the source of much weirdness.
67	* In ''Fanfic/TheStoryToEndAllStories'', the Nothing's arrival is indicated by dark, ominous clouds.
68	[[/folder]]
69
70	[[folder:Films -- Animation]]
71	* ''WesternAnimation/TheAdventuresOfIchabodAndMrToad '': During The Headless Horseman's entrance the sky turns burning red probably signaling danger.
72	* ''WesternAnimation/{{Aladdin}}'': Once Jafar takes full control and becomes a sorcerer, the sky over Agrabah turns red after a [[PurpleIsTheNewBlack brief purple phase]], and it stays that way until he's defeated.
73	* ''WesternAnimation/KungFuPanda2'': The sky is as red as rubies in Shen's introduction. Ironic, since red is the color of luck in China.
74	* In ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks'', after the Dazzlings summon their siren avatars, the sky turns from indigo to a threatening red.
75	* In''WesternAnimation/TheSecretOfNimh'', the sky temporarily turns red during Justin's fight with Jenner.
76	* ''WesternAnimation/WreckItRalph'':
77	** The "Out of Order" sign paints everything in Niceland tints of yellow and red.
78	** The sky of ''Sugar Rush'' turns incarnadine after the Cy-Bugs have caused enough havoc.
79	[[/folder]]
80
81	[[folder:Films -- Live-Action]]
82	* The skies of Transylvania in ''Film/BramStokersDracula'' are primarily blood-red in color.
83	* Somewhat parodied in ''Film/TheBurbs''. The film DOES take on a somewhat more creepy tone after that scene.
84	-->'''Ricky Butler:''' Green sky tonight... Green sky at morning... neighbor take warning.\
85	'''Ray Peterson:''' Green sky at night?\
86	'''Ricky Butler:''' Neighbor take flight?
87	* Fully justified in the Sci-Fi Channel movie ''[[Literature/Deathlands Deathlands: Homeward Bound]]'', as it's a sign the [[DeathWorld chem clouds]] are heavy. With [[HostileWeather acid rain]].
88	* ''Film/{{Flash Gordon\|1980}}'' (1980). The clouds in front of the plane Flash and Dale are in, which are part of Emperor Ming's attack on the Earth (fiery hail).
89	* ''Franchise/{{Godzilla}}'':
90	** ''Film/TheReturnOfGodzilla'': The red clouds and sky produced by the nuclear missile explosion in atmosphere, which is actually kind of pretty, if you forget what caused it in the first place.
91	** ''Film/Godzilla2014'': Done in for night time scenes of the places that Godzilla has demolished, as a result of all the burning buildings.
92	** ''Film/GodzillaKingOfTheMonsters2019'': The sky is ominously reddish-orange during [[MagmaMan Rodan]]'s first appearance, reflecting his extreme power as a force of nature and his wrathful personality.
93	* ''Film/GokeBodySnatcherFromHell'' starts off with a severe case of this.
94	* Referenced in ''Film/TheGreatRace''. Maximilian explicitly quotes the koan, only for the film to cut to the ensuing storm.
95	* ''Film/IndependenceDay'': The giant fireballs in the sky caused by the city destroyers entering Earth's atmosphere. Also, the sky of the destroyed cities takes on a dusty, reddish hue.
96	* To quote Legolas from ''Film/TheLordOfTheRingsTheTwoTowers''
97	-->'''Legolas:''' A red sun rises. Blood has been spilled this night.
98	* This happens in ''Film/SinCity'' in ''The Big Fat Kill'', when the girls of Old Town are revealed to have surrounded [[TheDragon Manute]] and his men in an alleyway and rain down a fire of bullets on them.
99	* ''Film/VoyageToTheBottomOfTheSea''. Justified when the Van Allen Belt is on fire. Well ok, it's actually ridiculous HollywoodScience, but leads to an impressive visual when the submarine surfaces to see icebergs melting as the sky burns.
100	[[/folder]]
101
102	[[folder:Literature]]
103	* ''Franchise/FactionParadox'': In [[EldritchLocation the Eleven-Day Empire]], the sky's always blood-red, like something's burning beyond the horizon, forever and ever...
104	* In ''Literature/FearNothing'' and ''Literature/{{Seize the Night}}'' by Creator/DeanKoontz, the world visited through the egg room in Fort Wyvern has a blood-red sky, fleshy black trees, and hellish {{puppeteer parasite}}s.
105	* In ''Literature/HereticsOfDune'' the sky of the planet Tleilax (home of the Tleilaxu masters, Face Dancers, Axolotl tanks, and a multitude of other dangerous and/or morally questionable things) is described as being an intense carnelian (a deep, reddish-brown) color.
106	* The World of Rod described in ''Literature/LabyrinthsOfEcho'' has red sky over one of its continents, not the most dangerous or safe. Theories vary, up to "the sky here reflects sands of Red Desert under it". In the Heart of the World ''any'' changes of sky color upset people. In the era of clashing dozens of magical orders, the sky was painted constantly, and just from statistics of celestial hues it was clear which one's adepts are stronger. Even the Great Magister of the only surviving order and a great aestheticist dared not to play with this (after the threat of magic overuse was gone): people remembering the civil war are still around.
107	* ''Literature/TheLordOfTheRings'':
108	** {{Mordor}} is blanketed by a perpetual red cloud cover, at least in the movies. The air was said to be poisonous there, so it's a similar idea. In the original books, it's not clouds, but masses of smoke from Mount Doom. Sauron deliberately summoned it up to hide under it, covering his preparations for his attack on Gondor (but ''also'' making "spy" hobbits harder to detect, which actually worries him).
109	** Also subverted in ''The Return of the King'' (book only) when, after the Ring is destroyed, Sauron rises as a vast anthropomorphic cloud of dark smoke from the Dark Tower and appears to threaten the armies of Gondor -- only to be swept away, impotent, by the wind from the West. Happens again in a very similar manner to Saruman at the end.
110	* In ''Literature/TheNightsDawnTrilogy'', given enough [[spoiler:possessors]] they will begin to use their [[RealityWarper reality dysfunction powers]] to create a red glowing cloud above their territory -- which, given the speed with [[TheVirus which they spread]] usually means a planet. This is a psychological urge for them, and a prelude to [[spoiler:removing the planet from the normal space time continuum]].
111	* Alluded to in [[Creator/ArthurMachen Arthur Machen's]] ''Novel of the White Powder''. Though it's implied to be nothing but an ordinary sunset, Francis Leicester cheerfully describing the sky as "as if the great city were burning in flames and [...] raining blood", while apparently considering fire and blood "a pleasant evening" is one of the first big signs that there's something seriously wrong with him. [[SlowTransformation It]] [[TheCorruption gets]] [[BodyHorror worse]].
112	* ''Raft'', the first published book of the ''Literature/XeeleeSequence'', takes place in a micro-galaxy in another universe (everything but life forms is smaller due to the higher gravitational constant). The galaxy is dying and must be evacuated. Guess what the most visible sign of the situation is.
113	* In ''[[http://slimebeast.com/forum/stories/red-sky-at-night/msg703/#msg703 Red Sky at Night]]'' by Creator/{{Slimebeast}}, the sky is remarked to turn red at sunset at least twice throughout the story of a cruise gone terribly wrong. "Red sky at night, sailor's delight" is invoked at the first sunset, in which the survivors use a life raft to escape whatever is leaving people dead in the water. The 2nd sunset is [[spoiler:after Graham's last hopes are dashed upon finding what he thought was land to be a giant mass of corpses, and he [[AteHisGun eats his flare gun]]. The narrator is revealed to be the entity causing all the doom, whose final remark is the sky turning a beautiful scarlet]].
114	* In the second ''Literature/WarriorCats'' book, the morning that [=WindClan=] arrives home, their medicine cat, Barkface, announces that the clouds are stained with blood, and the day will bring an unneccessary death. This comes true when Fireheart and Graystripe head home -- rather than taking the long way around [=RiverClan=] territory to get home like they're supposed to, they take a shortcut through it. A patrol spots them and starts a fight, and one of the [=RiverClan=] warriors dies when he falls into the gorge.
115	[[/folder]]
116
117	[[folder:Live-Action TV]]
118	* Just as in the comic version, in the Series/{{Arrowverse}}, red skies mean [[Series/CrisisOnInfiniteEarths2019 a crisis]] is coming!
119	-->'''Earth-66 Robin:''' "Holy crimson skies of death!"
120	* ''Series/DoctorWho'':
121	** "[[Recap/DoctorWhoS30E5ThePoisonSky The Poison Sky]]" has the sky turning red when it's set on fire to clear it of a poisonous gas spread by aliens.
122	** "[[Recap/DoctorWhoS30E15PlanetOfTheDead Planet of the Dead]]" involves the characters being stranded on a desert planet [[spoiler:comprised entirely of the deconstructed bodies of an entire civilisation]] and encountering what, from a distance, looks like a gigantic sandstorm heading their way. This in itself would be bad enough, but as it turns out [[spoiler:it's ''not'' a storm, it's a living swarm of billions upon billions of stingray-like creatures that survive by completely deconstructing and using the energy of entire civilizations -- as they have already done with this world.]]
123	* ''Series/TheFades'' features this in the final episode. [[spoiler:After Paul reopens Ascension, the final shot of the series is a [[PanUpToTheSkyEnding pan up to the sky]], indicating that [[SequelHook something very bad is about to happen]].]]
124	* In the finale of ''Series/{{MASH}}'', Klinger is admiring the reds from the setting sun when Potter says it would look a lot better if it was in the west. Turns out he's seen this before; a wildfire.
125	* In ''Series/OnceUponATime'', flashbacks in the episode "[[Recap/OnceUponATimeS1E8DesperateSouls Desperate Souls]]" show that the ongoing Ogre War in the Enchanted Forest has caused the horizon to turn blood-red, as if there was a perpetual unnatural sunset throughout the day. Rumple cites it as symbolizing all the child soldiers who have died during the war.
126	* In the aptly named ''Series/StargateSG1'' episode ''Red Sky'', the team accidentally "poisons" a planet's star when their [=MacGuyvered=] DHD lets their wormhole pass directly through it. Minutes after their arrival the star's light shifts towards the red end of the spectrum, and the locals - who are protected by the Asgard and follow Norse mythology - believe it to be the sign of Ragnarok.
127	* In the ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS2E1AmokTime Amok Time]]", Vulcan's sky is scarlet when [[PowerTrio Kirk, Spock, and McCoy]] arrive for Spock's wedding, almost as though it knows [[InvoluntaryBattleToTheDeath what will happen]] before our hapless heroes do.
128	* ''Series/Titans2018''. After the Titans shut down the factory Scarecrow was using to create his fear toxin, Commissioner Barbara Gordon [[BatSignal projects a giant T on the clouds]]. However Scarecrow goes to Plan B and [[WaterSourceTampering dumps a massive dose of fear toxin into the water supply]], whereupon Barbara looks up at the sky and sees the T is projected onto menacing red clouds.
129	* The end of the episode "Red Sky" in the ''Series/{{V\|2009}}'' 2009's remake when [[spoiler:Anna finds out her soldiers were blown up in her spaceship by Erica causing her to breakdown and scream.]]

135	* "The Unforgiving Blade" by Hammerfall.

145	* Jesus uses this phrase as the religious scholars asked him for a sign, rebuking them.[[https://www.biblegateway.com/verse/en/Matthew%2016%3A2 "Matthew 16:2"]]
146	* In Guatuso mythology the sky and all the heavenly bodies turned blood-red as a prelude to the global flood that transformed the earth.
147	[[/folder]]
148
149	[[folder:Tabletop Games]]
150	* ''TabletopGame/{{Cyberpunk}} RED'' gets its name from The Time of the Red, a period following the end of the Fourth Corporate War in 2023. The particulate debris from all the conventional destruction, wildfires, orbital strikes and the nuclear destruction of Night City stained the skies red for two years, which eventually died down to brilliant red sunrises and sunsets for the next decade. While this came after the war, it signaled that a long period of reconstruction was on its way, and that [[VideoGame/Cyberpunk2077 more problems were on the horizon]].
151	* Avernus (top layer of LawfulEvil plane in ''TabletopGame/{{Planescape}}''-based ''TabletopGame/DungeonsAndDragons'' cosmology) has it. Take war-torn wasteland, scrapyard, FireAndBrimstoneHell and mix unholy hybrid combining their worst traits -- it will be Avernus. And it's the ''least'' horrible of the Nine Hells.
152	* ''TabletopGame/GammaWorld'' adventure ''Alpha Factor''. One possible weather condition is "acid rain" (with real acid). It falls from an unusual storm system with red-tinged clouds.
153	[[/folder]]
154
155	[[folder:Theatre]]
156	* In ''Theatre/CesareIlCreatoreCheHaDistrutto'', a blood red moon and clouds are projected over the stage in the scene where Cesare confronts the two traitors.
157	* The lighting is done to invoke this in ''Theatre/{{Finale}}'', as the characters [[spoiler:walk into the burning sunset and to their deaths]].
158	[[/folder]]
159
160	[[folder:Video Games]]
161	* The final sequence of ''VideoGame/AssassinsCreedBrotherhood'' has this, as Ezio travels through Spain to face his nemesis.
162	* Upon starting the final battle against the titular GiantSpider in ''VideoGame/ChooChooCharles'' by placing his eggs into the artifact meant to destroy them, [[spoiler:Charles appears and absorbs the released energy to go OneWingedAngel]]. The sky turns a deep red in response to this and only turns back to normal after he's dead.
163	* In ''VideoGame/CommandAndConquerRenegade'', Nod's superweapon (a beacon that calls a [[SlapOnTheWristNuke nuke]]) turns the sky red before it strikes.
164	* The final battle in ''VideoGame/DragonAgeOrigins'' has this... though it might only be the burning city of [[spoiler:Denerim.]]
165	* When things really start going downhill in ''VideoGame/{{Drakengard}}'', the skies take on a hellish red hue. The sky doesn't just change color...it ''shatters into thousands of pieces'' to reveal the red beneath the blue.
166	* ''VideoGame/EarthBound1994'': Giygas is not really a cloud per se, but he is red and vaporous.
167	* ''Franchise/TheElderScrolls'':
168	** In ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', the skies over [[{{Mordor}} Red Mountain]] have been a swirling red blight storm ever since [[BigBad Dagoth]] [[PhysicalGod Ur]] [[KingInTheMountain reemerged]]. After you complete the main quest, the skies clear for the first time in centuries.
169	** In ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'', the skies of the [[IDontLikeTheSoundOfThatPlace Deadlands]] (the [[EldritchLocation Daedric plane]] of [[BigBad Mehrunes Dagon]], [[OurGodsAreDifferent Daedric Prince]] of [[DestroyerDeity Destruction]], and the closest thing to a FireAndBrimstoneHell in the setting) are red. This goes not only for the sky and clouds, but also the visible stars and nebulae. Within Mundus, the mortal plane, a red sky means you are approaching an Oblivion Gate. Expect to see some of Dagon's [[OurDemonsAreDifferent lesser Daedra]] [[LegionsOfHell minions]].
170	** Coldharbour is the realm of Molag Bal, Daedric Prince of [[TheCorrupter Domination and Corruption]]. It is said to have a BloodyBowelsOfHell aesthetic, and the sky is not only red, but actively ''on fire''. However, when you actually get to visit it in ''[[VideoGame/TheElderScrollsOnline Online]]'', this [[GameplayAndStorySegregation is not the case]].
171	** ''VideoGame/TheElderScrollsVSkyrim'':
172	*** Hircine's quest involves going to a valley where he's made blood-red moon appear, turning the sky red and compelling his worshippers to start HuntingTheMostDangerousGame. The quarry in question? The werewolf that gave you the quest, whom you can either fight alongside or hunt yourself. The sky returns to normal after either outcome is achieved.
173	*** The ''Dawnguard'' DLC revolves around an ancient vampire lord's plan to darken the sun forever so that his kin can walk the world without being WeakenedByTheLight. No matter which side you decide to join, once the quest line is completed, you can enact this plan yourself by shooting the sun with a special bow and arrows dipped in pure vampire blood. This results in the sky darkening and the sun turning into a black void surrounded by a blood-red corona for 24 in-game hours. It not only looks creepy as hell but also results in Death Hounds, gargoyles and vampire hunting parties spawning absolutely everywhere, which is most definitely not a good thing even if you're a vampire yourself.
174	* The rolling distant red clouds in the point and click game ''VideoGame/{{Exmortis}} 2'' which inspired this trope (found [[http://www.newgrounds.com/portal/view/303832 here]]). The player is racing against time to solve the puzzle and get out before the clouds get to him, these clouds actually being the Exmortis themselves and therefore very dangerous. While the red clouds indicate the Exmortis are approaching, a red ''sky'' is present throughout the game as a sign of the Exmortis' domination of Earth.
175	* In ''VideoGame/{{Iji}}'', the second time the [[PlanetKiller Alpha Strike]] is shown charging up at the end of the game, the sky is ominously red. However, that's because the scene takes place at sunrise, not due to anything about the Alpha Strike, since the first time we see it used, the sky is blue.
176	* ''Franchise/TheLegendOfZelda'':
177	** ''VideoGame/TheLegendOfZeldaOcarinaOfTime'':
178	*** In the Ganondorf-dominated future, Death Mountain is perpetually surrounded by a red ring of fire instead of clouds. Once the boss of Fire Temple is defeated, the fire goes away and is replaced by the standard cloud ring.
179	*** In the future, Castle Market Town and Ganondorf's tower are ''perpetually'' covered in brimstoney clouds and dark backgrounds.
180	** ''VideoGame/TheLegendOfZeldaMajorasMask'', the horizon takes on a red hue on the night of the final day. In the 3DS remake, the entire sky on the final night is blood red, complete with clouds of dark swirling energy.
181	** ''VideoGame/TheLegendOfZeldaTheMinishCap'': Vaati's EvilMakeover of Hyrule Castle includes turning the sky a vibrant shade of red red with black clouds everywhere, though it doesn't extend beyond the castle itself.
182	** ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' has the sky turn a bloody red every few days on the stroke of midnight, when Calamity Ganon uses his power to revive all the monsters you killed. The event is called a "[[BadMoonRising Blood Moon]]" because the moon turns blood red, and in the 15 in-game minutes (15 real-life seconds) before midnight the sky starts becoming filled with red sparks as a warning to the player. During the final phase of the final battle against Ganon, the sky turns red one last time... this game.
183	** ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'': In addition to the sky turning red when the Blood Moon is approaching the sky's zenith like in ''Breath of the Wild'', the game also shows the sky turning red when a cluster of Gloom Hands is sighted. During this state, Link's health is unable to recover from the effect of MaximumHPReduction caused by the Gloom. The sky goes back to normal when Link manages to escape the Hands; but if he defeats them all, Phantom Ganon will appear and the sky will continue glowing red; in this case, it'll be necessary to defeat the boss in order to finally put an end to the redness. The Blood Moon also appear in a couple cutscenes, one when [[spoiler: Ganondorf takes the Secret Stone,]] one when [[spoiler: he uses it to conjure an army of monsters,]] and one when [[spoiler: a disguised Phantom Ganon appears at Hyrule Castle.]] Then, finally, the Blood Moon and red sky reappear one last time [[spoiler: when Link goes in for the kill against the Demon Dragon.]]
184	* In ''VideoGame/{{STALKER}}'', repeated lightning strikes and the sky shifting to red clouds means an emission is in progress, and it's high time to find shelter if you want to avoid ([[PlotArmor almost]]) certain death, [[OurZombiesAreDifferent or worse]]. During the course of the emission, it's guaranteed that ''all the light in the Zone'' will turn a vivid blood red for a second or two.
185	* In the original ''VideoGame/StarFox/Starwing'', the first level Corneria is different for each difficulty setting/route. On the third and hardest one, the normally blue sky is replaced with an ominous red one, presumably from the sunset (or sunrise, as the 'normal' boss has a "cameo" as a set of parts being carried around), and the level has hiked up the difficulty.
186	* ''Franchise/TouhouProject'':
187	** This trope is the driving force behind ''VideoGame/TouhouKoumakyouTheEmbodimentOfScarletDevil'': a red mist has covered Gensokyo and is strong enough to block out the sun.
188	** ''VideoGame/TouhouHisoutenScarletWeatherRhapsody'' has red clouds show up at the same time as a series of bizarre weather events... and earthquakes.
189	* ''VideoGame/{{Warcraft}}'':
190	** When the orcs started worshiping demons and practicing warlock magic, they inadvertently turned the sky of their home world from blue to red. Good things did ''not'' result.
191	** In the final Orc mission of ''Warcraft III'', which pits Thrall's New Horde and human allies against Grom Hellscream's corrupted Warsong Clan, the red sky heralds the demons called to reinforce Grom -- [[DeathFromAbove falling Infernals]].
192	--->'''Jaina:''' Thrall! The sky is ''[[OhCrap burning!]]''\
193	'''Thrall:''' This is no natural storm. [[OhMyGods Blessed ancestors...]] Everyone, brace yourselves!
194	* Similarily in the ''VideoGame/WorldOfWarcraft Cataclysm'' expansion, [[BigBad Deathwing]] flies around at random scorching cities and other areas, incinerating anyone unlucky enough to be outside. His coming is noted by a dramatic change in the sky from "clean blue skies" to "red and on fire". Unfortunately this is actually a [[SubvertedTrope subversion]] because there's an [[DeathIsASlapOnTheWrist achievement for dying to Deathwing's flames]]. A [[http://www.thedailyblink.com/2010/11/double-secret-reverse-psychology/ webcomic took note]] on the absurdity of it all.
195	* The final battle in ''VideoGame/LuigisMansion1'' against King Boo (and Mecha Bowser) takes place among orange/red flame-like clouds on the floating rooftop of the mansion.
196	* The level ''Boogie Mansion'' in ''VideoGame/WarioLandShakeIt'' has a background of ominous purple trees and clouds.
197	* The AfterTheEnd CrapsackWorld of ''VideoGame/{{Baroque}}'' has a blood-red sky.
198	* The sky turns red on the 6th and Last Days of ''VideoGame/DevilSurvivor'' [[spoiler:due to the barriers between the Demon World and real world breaking down]].
199	* In the final chapter of ''VideoGame/TalesOfMonkeyIsland'', the Caribbean sky is turns red, as part of [[spoiler:[=LeChuck=]'s latest]] bid to conquer the seven seas.
200	* In ''VideoGame/MetroidPrime2Echoes'''s [[DarkWorld Dark Aether]], taking some energy from one of the dark areas turns the sky from purple to red.
201	%%* In ''VideoGame/SecretOfMana'' the sky is red when the Fortress has risen. (ZCE)
202	* The Director's Cut of ''VideoGame/{{Scratches}}'' replaces the sky's dark gray hue of the starting scene with a dark red one.
203	* The recent ''VideoGame/CallOfDuty'' games from ''VideoGame/ModernWarfare'' onward seem to adore blood-red skies. Whenever something horrible is happening, whether it's a nuclear bomb or a bloody street battle in Hue City, the skies are an ominous shade of red. Sometimes subverted when a terrifying moment or something plot-critical happens under clear blue skies.
204	* The Wii version of a ''VideoGame/ABoyAndHisBlob'': In the first boss level, the sky is an orange-red hue. The sky also turns red during fights against a final boss and normal again when it is defeated.
205	* The second half of ''VideoGame/FinalFantasyVI''. However, it's because of the pollution that has reached the sky due to the cataclysm making it impossible to see anything but red, and it's more of a reddish-orange, though if pollution were to ever get ''that'' bad, it would certainly be enough to take warning.
206	* In ''VideoGame/FinalFantasyVIII'', Esthar's sky turns red and monster-infested resulting from the Lunar Cry triggered by the Lunatic Pandora.
207	* In ''VideoGame/CityOfHeroes'', the skies over most of Paragon City are a glowing blue because of the War Walls - leftover [[HandWave Hand Waves]] for why you couldn't freely run from one zone to another except in designated spots. Slightly varied in other areas, and in the Rogue Isles and Praetoria, the areas of the two expansions. But, when certain conditions are met (specifically a Halloween event that pops up semi-randomly after a certain quest is completed any time of the year) [[ZombieApocalypse zombies invade]] one of the zones. Guess what color the sky becomes?
208	* In ''VideoGame/Persona3'', the sky turns green and all water turns to blood during the Dark Hour.
209	* In ''VideoGame/PokemonLegendsArceus'', [[spoiler:during the climax of the game the sky is turned red by a frenzied [[OlympusMons Dialga/Palkia]], leading to the FinalBoss battle.]]
210	* A red sky in ''VideoGame/HalfMinuteHero'' means that you have less than ten ''seconds'' to finish your quest before the stage boss casts a spell to destroy the world.
211	* Lampshaded in one level of ''[[http://www.kongregate.com/games/TheGamesCenter/legitimate-td Legitimate TD.]]'' The level preview says "That is never a very good thing, is it? The whole 'red sky' thing." [[spoiler:Then comes a [[BigBulkyBomb nuke that takes up almost half the screen.]]]]
212	* In ''VideoGame/StarControlII'', the Ur-Quan slave shields have a red color. Guess how the sky looks from the surface of, for example, slave-shielded Earth-something mentioned by Starbase Commander Hayes.
213	* ''VideoGame/{{Doom}}'' is a fan of red skies in the last third or so of the games. The third episode of the original game, Inferno, set in Hell itself, has a fittingly blood-red sky. The fourth episode, Thy Flesh Consumed, has a mostly sunset-yellow sky tinged with red. In ''VideoGame/DoomII'' it goes further, displaying nightmarish mirages of bones and skulls fused together, and in ''The Plutonia Experiment'' of ''VideoGame/FinalDoom'' (where the sky is blood red as early as [=MAP12=]), the {{skybox}} seems to be made of meat or muscle strings. In a few levels of ''VideoGame/Doom64'', the sky is taken over by bright red fire.
214	* The end of the beta for ''VideoGame/TheMatrixOnline'' features the sky turning red ''[[http://static.giantbomb.com/uploads/original/0/5872/278852-33678258.jpg with eyes,]]'' signifying that the Machines were watching as they prepared to reboot the Matrix.
215	* Most of ''VideoGame/SuperTanookiSkin2D'' is spent with a red sky. It turns blue once you get your skin back from Mario.
216	* ''Franchise/TombRaider'':
217	** ''VideoGame/TombRaiderTheLastRevelation'' uses this in its final stages, by the time mythological monsters have largely replaced human and animal opponents, and Set is about to reform.
218	** ''VideoGame/TombRaiderII'' uses an unnaturally-colored green sky in the Floating Islands.
219	* ''VideoGame/FalloutNewVegas'': The Sierra Madre is always overcast by a red toxic cloud, adding to the unsettling ambiance.
220	* The last part of story mode in ''VideoGame/MortalKombatX'' has Shinnok absorbing Earthrealm's energy while corrupting it with his own life force. Shinnok's actions change the sky from normal to a deep, bloody red. Only when Shinnok is defeated and Raiden purges the corruption does the sky return to normal.
221	* In ''VideoGame/{{sora}}'', you have to fight [[WoobieDestroyerOfWorlds Star Breaker]] at the end of stage 6, up in the sky which has turned red, and it remains the same in stage 7, during the final battle.
222	* Inferno's skies and clouds in ''VideoGame/Bayonetta2'' are of a lovely blood red coloration. Needless to say, it is a ''very'' dangerous place.
223	* Zig-zagged between straight example and {{inver\|tedTrope}}sion in ''VideoGame/{{Darkwood}}''. The bright orange light of sunset (around [=5PM=]) is a warning for you to begin hauling ass back to the hideout; by contrast, if you can see the outside (between [=6AM and 8AM=]), the blood red light of sunrise is a relieving sign that the [[NiceDayDeadlyNight deadly nighttime]] is about to end -- it even comes accompanied by a motivating rising note.
224	* In the days before the servers were shut down to remake the game from scratch, ''VideoGame/FinalFantasyXIV'' had the artificial moon, Dalamud, slowly fall towards the earth. By the final days, Dalamud was glowing a bright red while the sky turned into an unnatural mixture of yellow and gray.
225	** During the climactic parts of the ''Endwalker'' expansion, various skies turn red [[spoiler: during the attempted End Days caused by a corrupted Meteion]], complete with what look to be meteor showers.
226	* ''VideoGame/VersusUmbra'': The final planet in First Strike, Nivaga, has a red sky.
227	* ''VideoGame/HostileWaters'': The game has a red sky at all times, which turns redder when you die.
228	* In ''VideoGame/Ashes2063'', the sky in the City after the [[PlayerCharacter Scavenger]] leaves the settlement of Michonne Circle is crimson red and full of lightning because of a radiation storm. It's not just for show -- the radiation counter will keep increasing whenever you're out in the open, and the only ways to prevent poisoning is to duck inside a building or use a [[FantasticRadiationShielding Purge stim]].
229	* In ''VideoGame/DontEscape: 4 Days to Survive'', if you get within an hour or two of time running out on Day 4, the sky turns red as the moon comes closer to Earth. (Unless you deliberately waste time, this can only be seen if you have ''really'' bad time management or are going for the Mostly Walking achievement, where you can't use the car.)
230	* ''VideoGame/PhantasyStarOnline2''
231	** A variant occurs on the ARKS vessels whenever an urgent quest starts, as the vessels' interiors will take on a red hue with warnings flashing all over the place.
232	** On Harukatan, when Magatsu is released from its seal, the skies turn red, and ARKS has to fight it before it can destroy the Daybreak Province.
233	** Happens twice on Naverius. First when Dark Falz [Elder] was released from its prison, and launched an assault on the Oracle Fleet. [[spoiler:The second time was when the Profound Darkness was one the verge of being revived before [Persona] sealed it away again.]]
234	** On Omega, [[spoiler:when Elmir was in the processing of trying to revive the Profound Darkness, using Harriet as a vessel]], the skies above the planet had turned red.
235	** In ''[[VideoGame/PhantasyStarOnline2NewGenesis New Genesis]]'', whenever an urgent quest comes up, the skies above planet Halpha will take on a red hue, signifying that a powerful DOLLS is in the area.
236	* In ''VideoGame/DinoRun'', the sunlight gets overshaded by [[https://dinorun.fandom.com/wiki/Wall_of_Doom?file=Doom_%21_mark.jpg red and black]] as a sign of the AdvancingWallOfDoom approaching.
237	* In ''VideoGame/AmidEvil'', the skybox for [[ShatteredWorld the Arcane Expanse]] gets {{Palette Swap}}ped to warmer colors in each successive level. The trend culminates when you reach the BossOnlyLevel, whose sky is a very bright shade of red and features a DualBoss fight against a pair of [[MadeOfEvil Void monsters]] that some corrupted wizards summoned.
238	* In ''VideoGame/Splatoon3'''s [[MultiMookMelee Salmon Run]] mode, the sky turns tomato-red when a [[{{Superboss}} King]] [[TimeLimitBoss Salmonid]] appears, and is always deep crimson during a Big Run, when the [[TheHorde Salmonids]] invade [[HubCity Inkopolis and Splatsville]] instead.
239	* One of the first signs in ''VideoGame/{{Viewfinder}}'' that the real world is nowhere near as healthy as the virtual world you explore comes up when you need to reboot the machine generating the latter; a quick look outside to the city shows the sky a rather ominous shade of crimson. In fact, this ends up being your player character's main motivation--to find a device within the virtual space that can restore the climate to something safe for humanity.

241
242	[[folder:Visual Novels]]
243	* The DarkWorld of ''VisualNovel/ElevenEyes'' is signified by a red sky and a [[WeirdMoon black moon]] that, besides its color, is immensely huge and hanging over the city.
244	* [[spoiler:After society collapses and the world is reduced to war, chaos, and despair,]] the skies in ''Franchise/{{Danganronpa}}'' are almost perpetually red.
245	* ''VisualNovel/VirtuesLastReward'': The total lunar eclipse seen in several endings [[spoiler:is actually Earth circa 2074, as viewed from the Moon. Thanks to the fires and destruction caused by the Radical-6 pandemic and the antimatter explosions, the atmosphere was shrouded in dust and ash, plunging the world into a nuclear winter that lasted seven years and killed millions of plants, animals and humans. By 2036, things began to clear up a little, but even decades later, Earth is still largely a wasteland and has so much pollution in the atmosphere that the planet looks red from space.]]
246	[[/folder]]
247
248	[[folder:Web Animation]]
249	* ''WebAnimation/BrokenSaints'' loves this one. The original rhyme for sailing is referenced by Gabriel in Chapter 15, Act 1, before a literal storm. And during the final two chapters, [[spoiler:when the EvilPlan is about to unfold/unfolding]], the sky is a scary, unnatural red for the metaphorical storm.
250	* ''WebAnimation/MadnessCombat'': The sky over Nevada begins to take on a solid red coloration after [[ItMakesSenseInContext the Sun itself spontaneously incarnates as a person and gets murdered with a street sign by the main protagonist]]. At first, this event plunges the region into [[TheNightThatNeverEnds a seemingly-permanent night]], but not long afterward an ominous red glow manifests which eventually fills in the entire sky. As it does so, it also creates a disturbing "TV static" effect across the whole sky at one point.
251	[[/folder]]
252
253	[[folder:Webcomics]]
254	* In ''Webcomic/{{Furmentation}}'', when the demons attack.
255	* The homeworld of the Cherubs in ''Webcomic/{{Homestuck}}'' is near a red supergiant, coloring the sky appropriately red. Dave also lived under a red sky before he entered the Medium.
256	[[/folder]]
257
258	[[folder:Web Original]]
259	* ''Blog/HamstersParadise'': Subverted. At certain times of day, the planets' [[BinarySuns second sun]] Beta is the only one visible in the sky and being a red dwarf, this caused the surface to be bathed in an ominous looking dim red light. It is no more dangerous than any other time of day and some animals have evolved to be more active at this time to exploit the relative safety, often gaining red coloration in the process so to better blend in.
260	[[/folder]]
261
262	[[folder:Western Animation]]
263	* The season 4 finale of ''WesternAnimation/TheAdventuresOfPussInBoots'' involves an AncientEvil being summoned, and with it a blood red sun so strong that everything is colored red by it.
264	* ''WesternAnimation/{{Amphibia}}'': In "True Colors", during the moment [[spoiler:Andrias reveals his true motives and the Newtopia Castle begins floating like a fortress,]] the sky turns fiery orange-red.
265	* The sky turns red twice in ''WesternAnimation/AvatarTheLastAirbender'': the first time is when [[spoiler:Zhao captures the moon spirit]], and the second is when [[spoiler:Sozin's comet is passing by]].
266	* In ''WesternAnimation/BatmanTheAnimatedSeries'', Gotham City is such a nightmare dreamscape, the night sky is ''always'' red.
267	* ''WesternAnimation/BigCityGreens'': In "Chipocalypse Now" when Big Coffee and the apartment complex are blown up by Chip Whistler, the sky turns an infernal red.
268	* ''WesternAnimation/TheCrumpets'': At least two episodes end with a black silhouette of the Crumpet house under a red sky and [[spoiler:the Crumpet family screaming due to serious threats where deaths are imminent]].
269	* ''WesternAnimation/GravityFalls'' does this starting with the episode "Dipper and Mabel vs The Future". [[spoiler:When the rift to Bill Cipher's world opens, the sky turns a murky red. This marks the beginning of Weirdmaggeddon, and Bill is more powerful and dangerous than he's ever been before. Subverted in "Escape From Reality" when the forcefield keeping Bill and his mooks inside the town is revealed: the sky is actually normal, it's just that the apocalypse had given everything inside a red tint, making the sky ''look'' red from within the town.]]
270	* ''WesternAnimation/IHeartArlo'': During the FinalBattle against the [[EldritchAbomination Bog Lady]] in "The Uncondemning", the sky turns a very faint red, starting from the point Arlo escapes from the Heart with the girls and the Bog Lady begins to go OneWingedAngel.
271	* ''WesternAnimation/JackieChanAdventures'': In the VillainWorld AlternateTimeline where the Demon Sorcerers reign, the sky is more often than not a grim, sickly-looking orange palette. In the Season 5 finale, Drago literally creates an overcast, bloodred sky over San Francisco when he's preparing to unleash HellOnEarth.
272	* Any time something dangerous or scary is about to happen in ''WesternAnimation/{{Kaeloo}}'', the sky turns red.
273	* The skies are red on some episodes of ''WesternAnimation/TheMask''.
274	* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
275	** In "[[Recap/MyLittlePonyFriendshipIsMagicS4E26TwilightsKingdomPart2 Twilight's Kingdom - Part 2]]", from the moment [[spoiler:the Library Tree is destroyed]] and during the entire Twilight vs. Tirek showdown, the previously blue sky turns red and dark.
276	** In "[[Recap/MyLittlePonyFriendshipIsMagicS5E25TheCutieRemarkPart1 The Cutie Re-Mark - Part 1]]", the flashback showing the return of King Sombra and his enslavement of the Crystal Ponies is under an ominous red sky. Justified, given his FisherKing abilities.
277	** In "[[Recap/MyLittlePonyFriendshipIsMagicS9E2TheBeginningOfTheEndPart2 The Beginning of the End - Part 2]]", the sky turns a murky red-orange when Sombra takes over Equestria and mind-controls the Mane Six's friends and relatives.
278	* ''WesternAnimation/ThePowerpuffGirls1998''
279	** The episode "Tough Love" has the sky turn red when HIM's evil influence is spread throughout Townsville.
280	** In "Speed Demon", the girls enter a dystopian future where the girls never protected Townsville for ''50 years''; in this BadFuture, the sky is threatening vivid red.
281	* ''WesternAnimation/StormHawks'': Terra Cyclonia's sky is red. That's how you know it's evil. The crystals used by the Cyclonians also seem to change the color of the sky to a degree, which would explain Cyclonia's unique horizon.
282	* In ''WesternAnimation/TheSmurfs'' episode "Lost Smurf", a shifting multicolored sky portends a danger that only Grandpa Smurf knew about -- a mysterious haunted castle that has taken Nanny Smurf away when she went after him.
283	* ''WesternAnimation/StevenUniverse''
284	** In "[[Recap/StevenUniverseS1E2LaserLightCannon Laser Light Cannon]]", the sky turns bright red as the Red Eye comes crashing down onto the beach.
285	** Inverted in "[[Recap/StevenUniverseS1E48TheReturn The Return]]". [[spoiler:The nearing Homeworld-ship turns the sky a luminescent green.]]
286	* There is a reason the DarkerAndEdgier latest seasons of the '80s ''WesternAnimation/{{Teenage Mutant Ninja Turtles\|1987}}'' cartoon were known as the ''Red Sky'' seasons.
287	* ''WesternAnimation/TeenTitans'' used this trope for the three part finale of the season 4 Raven arc. It was for the [[AfterTheEnd post-prophecy]] world where everyone was [[TakenForGranite turned to stone]].
288	* ''WesternAnimation/RegularShow'': Whenever the gang is in danger, the sky pretty much always turns red/pink.
289	[[/folder]]

291	[[folder:Real Life]]
292	* There are known to be places in the world where poisonous fumes and fogs hang in low gullies -- many animals have died by wandering into these places and not getting out fast enough.
293	* Smog can sometimes cause the sky to turn red.
294	* Red (or at least reddish) skies can happen when there's a big fire during a cloudy day or night.
295	** Or after a large explosion. The reasoning is the same: huge amounts of particulates in the air (ash for the fire, dust for the explosion).
296	** [[https://www.deseret.com/u-s-world/2020/9/10/21430397/california-wildfires-orange-sky-photos The 2020 California wildfires have turned the sky red,]] particularly in the UsefulNotes/SanFrancisco area.
297	* The traditional saying "red skies at night, sailor's delight; red skies in morning, sailor take warning" (Alternatively, "shepherds delight", and with similar sayings in other languages.) According to Website/TheOtherWiki[='s=] entry [[http://en.wikipedia.org/wiki/Weather_lore#Red_sky_at_night Red Sky at Night,]] it's because weather systems usually move from west to east. Stable air masses scatter blue light more, making the sky red. If it is on the west, stable weather is coming, and if it is on the east, it is already past. This phenomenon is even mentioned in Literature/TheBible, making it OlderThanFeudalism.
298	* [[http://en.wikipedia.org/wiki/2009_Australian_dust_storm The 2009 Australian dust storm,]] especially during the early hours of the morning in New South Wales and inland Queensland.
299	* Less ominously, this also can happen on cloudy nights when there is snow on the ground, or on particularly rainy ones with heavy cloud cover. The clouds take on a slightly red tinge. Particularly thick or heavy snowfall can result in the sky becoming orange or even slightly pinkish, as snow's excellent reflective properties result in longer wavelengths of visible light being bounced about everywhere.
300	** [[https://polymathically.wordpress.com/2015/05/16/weekly-photo-challenge-divisadero-at-dusk For example, a sunset affecting clouds over San Francisco.]]
301	* The clouds can also glow reddish if overcast in a city with enough street lights, especially orange [[https://en.wikipedia.org/wiki/Sodium-vapor_lamp sodium-vapor lamps]] prevelant in many cities, resulting in a surprisingly bright night that almost invokes HollywoodDarkness.
302	* Planes flying above the clouds at times close to sunset may fly through bright orange skies as well, as the increased height means the sun may still be visible just above the horizon.
303	* Pretty much the sky of any planet that orbits close to either a red giant or red supergiant star, like with the case of Earth 5 billion years in the future when the Sun itselfs starts to become a red giant before completely engulfing the planet.
