When eye became a speedster in period 4, event 16, «operate eye, operate,» she was given a distinct costume through the Flash — plus a special colors.
When Iris West-Allen (Candice Patton) gotten Barry Allen’s (give Gustin) abilities in The Flash season 4, occurrence 16, «operated, eye, operate,» she was handed a distinct search from this lady partner — like her own special purple lightning effects. The reason why Iris got stylized so differently from the woman husband and masked champion, named «The Flash,» was never ever completely researched in-universe; but there are several buff ideas why — and a narrative reason that makes complete sense as an aesthetic behind-the-scenes decision.
The Flash will be the 2nd tv show in the CW’s Arrowverse, which started with Arrow in 2012.
The Flash observe the escapades of a forensic researcher who develops superhuman increase capabilities after a fresh particle accelerator explodes. Based on the dynamics from DC Comics, The Flash shows a determination to divert from the provider materials, and check out center ideas with its very own ways — such as the characteristics of Barry’s rate, just how superspeed and times vacation operate, therefore the notion of the «Speed power.»
Most fan theories regarding Iris’s purple lightning indicate eye’s relationship aided by the rate power, since this is considered the most clear difference between this lady and Barry. The actual science behind the real difference had been never explored fully when you look at the Flash, largely because eye decided not to manage having meta-human forces towards the end of this event. Narratively speaking, but Iris’s unique purple super had been mindful possibility: it had been completed to hint on character of this «mystery girl» observed earlier on in period.
The Reason Why The Flash Gave Eye Purple Lightning
In a job interview with TV instructions, exec music producer Todd Helbing verified that the costume outfit choice and super colors useful Iris in «Run, Iris, operate» had been made for «a particular explanation,» alluding to a huge expose after the growing season. Definitely, the season 4 finale contained a long-awaited response to which the strange feminine speedster ended up being which kept showing up through the period. Initially participating during the situation on Earth-X crossover, the lady displayed common familiarity with professionals Flash, and had speedster abilities — characterized by purple and yellow lightning. The finale verified what enthusiasts got already suspected using the clues: she was Barry and eye’s youngster from future, Nora West-Allen. Iris’s purple lightning in event 16 ended up being hence an easy method for your show’s imaginative personnel to hint a link between Iris together with mystery female.
What Iris’s Imperial Lightning Implies For The Flash
In-universe, the primary reason for eye’s super tone is actually considerably obvious. While eye’s purple super is never talked about at length, its different shade likely enjoys something to manage together relationship making use of the Speed Force. The Speed Force try a mysterious sentient entity that is out there outside of the multiverse and items speedsters due to their capabilities. Whilst it can reveal alone into a physical form being communicate, mostly, it is out there as an extra-dimensional area. Barry has seen the accelerate energy on various occasions regarding the show, and was even stuck indeed there for a while in a personal experience comparable to the Christian notion of purgatory. In Flash, speedsters like Barry and eye’s sibling Wally West (Keiynan Lonsdale), which goes on «Kid Flash,» accomplished their own link with the performance power in the same way, and thus both generate yellow lightning as they work. Other speedsters during the series, but produce a special coloured lightning — like Iris’s purple variation.
Since Iris and Wally include siblings, this indicates unlikely that genes would be the reason behind eye’s specific super tone; thus, their varying relationships using performance force was a most likely explanation. Even though the different super could have related to their gender, this couldn’t explain the reason why the Flash’s child Nora possess purple and yellow super. Both Wally and Barry was given their particular meta-human influence for the reason that an accident that place them in a coma. Iris, conversely, obtained their forces whenever a 
meta-human transported Barry’s influence to her. You might say, Iris’s superhuman speeds simply granted to their fully-formed, as opposed to becoming developed, because it’s in other speedsters. The Flash currently founded that speedsters which get her skills through using medication, or through the Negative Speed energy, develop blue and red super correspondingly, therefore it is reasonable for Iris’s super for a similarly distinct shade.
