History YMMV / RainbowHigh

** Of course, Amaya's wave 2 appearance is often pitted against her original look. There is no clear answer to which look the fandom overall prefers.

*** Also (believe it or not) with fans of the older ''Toys/{{Lalaloopsy}}'', the toyline's commonalities with its spin-off ''Lalaloopsy Girls'' being the bond instead. In addition, both ''We're Lalaloopsy'' and the full ''Rainbow High'' series can be [[Creator/{{Netflix}} found on the same platform.]]

* HoYay: [[HoYay/RainbowHigh Here.]]

* ItWasHisSled: [[spoiler:Bella's expulsion and Amaya taking her place]] became common knowledge in the fandom overnight.

** "Poppy the Background Character", as she's usually being put OutOfFocus and [[FlatCharacter lacking depth compared to other main characters]].

* {{Moe}}: Sunny, of course.

* NeverLiveItDown: Despite making amends offscreen, many fans still don't forgive Violet for her nasty behavior towards Sunny in episode 1.

* OvershadowedByControversy: What marred the hype for Rainbow High's first wave's release was its noticeable lack of diverse skin tones, Skyler [[RaceLift having a darker complexion in the animation]] not helping the case. When wave 2 was leaked and Krystal's doll was revealed to have the same skin tone as Skyler, many fans demanded that her doll be made with a darker skin tone (which the line still lacked at this point). MGA responded and pulled the original Krystal in favor of giving her such, and she was released later than the other wave 2 characters.

* TheScrappy: Colin. Skyler doesn't even forgive him or try to end off their relationship as AmicableExes at the end of episode 6. The show, or at least the animators of "Amaya's Discovery", also seems to view him as [[ButtMonkey this.]]

* ShipsThatPassInTheNight: When River was leaked fans instantly paired him with Skyler and/or [[HoYay Aiden]] even ''before'' his name was revealed. Even though he [[spoiler:canonically crushes on Amaya.]]

* SurprisinglyImprovedSequel: Safe to say ''Rainbow High'' is more popular than ''Rainbow Surprise'' and ''Poopsie'' combined.

* TearJerker: ''Everything'' about [[spoiler:Bella being expelled. While Bella was well aware of the consequences of breaking the rules and [[ForegoneConclusion her leave was a given since the first episode]], her being mercilessly expelled out of the school was gut-wrenching to watch. Especially considering she was such a core member of the runway group and had such a close relationship with Jade, who likely feels guilty as she ultimately couldn't prevent her from breaking the rules. Meanwhile, Amaya is finally accepted to her dream school, only to find out the reason she got out of the waitlist was that Bella's leave left a free spot. The already insecure Amaya cannot help but feel she's only there to be ''Bella's replacement''. You really can't help but feel sorry for ''everyone'' involved, even [[JerkassWoobie Jade]].]]
* TheyChangedItNowItSucks: As of late 2023, the franchise softly rebooted to have more fantasy elements, and even brought back creature designs and the slime gimmick from ''Toys/{{Poopsie}}''. Needless to say, fans were ''not'' happy.

* TheWoobie: Sunny in "When the GLAM Meets The Fan". Fortunately Violet drops the attitude and they get back on good terms.

** [[spoiler:Bella]] in "Bella's Night Out". Despite [[spoiler:her [[TheBusCameBack triumphant return]]]] in the season one finale, "Welcome Back, Bella!" shows that her reputation has been marred by her expulsion, and becomes overwhelmed with questions about her situation.

** Lou Wright is canonically a strict, by-the-book fashion teacher. In the fanbase, she’s a tyrannical ''authoritarian'' of a principal. And with [[UnfortunateImplications the noticeable lack in dark-skinned students]] and [[spoiler:since her second major appearance saw Bella’s expulsion and the separation of the same-sex FanPreferredCouple]], a number of fans have run with her being an extreme bigot... [[BoomerangBigot in spite of the fact that Wright also has significantly dark skin]].

* HoYay / LesYay: [[HoYay/RainbowHigh Here.]]

** Fans would have rejoiced with Kia's appearance in "The Vi-Life", if it weren't for [[ButNotTooBlack her downplayed baby hairs and unexplained change from brown eyes to purple.]][[note]]While the series is no stranger to TechnicolorEyes, along with Karma Kia is one of the few characters with brown eyes.[[/note]] This was later fixed in season 2.

** The entire school itself is occasionally (semi-jokingly) interpreted as a BoardingSchoolOfHorrors due to its rather nonsensical and draconian policies, coupled with its questionable prison-like design. Students can be expelled for any number of reasons, including failing a single project or photographing their own work; visiting home on the weekends isn't allowed and there's seemingly no system in place to help kids deal with homesickness; the administration never gets involved in social situations that would very much merit teacher involvement in real life; and the workload and the hands-off approach of the staff seems much more appropriate for college than high school. Most of it can be attributed to the RuleOfDrama, as well as the fact that the toyline is primarily aimed at children who have never been to high school and are young enough to view it very idealistically, but fans still like pointing out how [[SuckySchool awful it'd probably be]] to attend Rainbow High IRL.

* GermansLoveDavidHasslehoff:
** According to Google Trends, the toyline is fairly popular in the UK, Ireland, and Australia. It also has a sizable following in some Central European and Latin American countries.

* AuthorsSavingThrow:
** Later episodes downplay Violet's [[BitchInSheepsClothing two-faced nature]] towards Sunny from the first few episodes, which had made her divisive in the fandom.
*** Likely to satiate criticisms concerning her lack of CharacterDevelopment despite having plentiful of screen time, "Amaya's Time" shows Violet asking River and Amaya's consent to post about [[spoiler:their first date]], which shows she has learned her lesson about filming with consent since "Going Viral".
** Krystal Bailey was given a darker complexion[[note]]Originally she was supposed to have the same skin tone as Skyler and Avery[[/note]] due to the backlash surrounding the lack of diversity in wave 1.
** "A Dorm With A View" must be the answer to the criticism concerning Poppy's lack of focus in recent episodes and [[FlatCharacter her lack in characterization.]]

* AlternateCharacterInterpretation: Sunny is widely interpreted to be neurodivergent.

* WereStillRelevantDammit:
** The characters unironically shout “Yaaas!”, Poppy and Violet often the culprits of this.
** Ruby does the ''{{VideoGame/Fortnite}}''-popularized “shoot”/“hype” dance in "Going Viral".
** In the same episode Jade also does the highly popular dance for “Say So” by Doja Cat, but due to the animation for it being less smooth many didn't notice. Then ''everyone'' does the “Say So” dance in the animated music video for “Turn Your Color Up”.

* LoveToHate: The De’Vious Twins, the BigBadDuumvirate of the Rainbow High social pyramid introduced in season two. They’re haughty, smug, and the fandom can’t get enough of them.
* HoYay / LesYay: [[HoYay/RainbowHigh Here.]]

* ItsShortSoItSucks: A common complaint about the webisodes is that they’re extremely brief, which is typical for webseries [[MerchandiseDriven tied to toylines]]. However, it’s detrimental in this case as the series was marketed promising high stakes and dramatic arcs, however they’re typically resolved in the next episode.

* UncannyValley: The artstyle may throw off some people, especially in its CGI form where everyone is given detailed teeth.
** Some find the "Fantasy Friends" spinoff figures unintentionally creepy. Then again, it's a carry-over from ''Poopsie''.
