Since magic doesn't work in the TVA, why didn't Loki turn blue? The answer is a bit complicated but the simple answer is because Odin's magic cannot be reversed.
In the same way, Odin's spell on Loki continued to affect him, preventing Loki from transforming back to having blue skin both after Odin's death and in the TVA Office in Loki.
He's the half–Frost Giant half-brother of Thor who has been conflicted about his place on Asgard since birth. (Remember: Odin literally turned his son's skin from blue to white when he was a baby and kept Loki's parentage hidden from him until he was an adult.)
While of jotun descent, Loki always was supposed to be the runt of the litter, so he likely would've never grown to giant size, and his skin does naturally go frost-giant-blue when he's exposed to cold. Maybe other giants also go pale when they warm up, who knows.
However, in the comics, Loki has a blue Jotun form up until Odin finds, which fans never see in the MCU. It would make sense that Loki would be blue or at least have a blue form, but it's understandable why the MCU cut that part out by making Odin wave his hand over him and disguise his blue skin.
The Norse god of Mischief, otherwise known as Loki, is associated with darker colors such as black, gold, yellow, and dark green. You will never see Loki depicted in bright colors and it is very rare to see him depicted wearing white.
Cryokinesis - Due to his Frost Giant heritage, Loki also technically has the ability to manipulate and control ice like his Jotunheim brethren. However, Loki has a complicated relationship with his Jotun blood, as he was abandoned by his people and raised to hate the Frost Giants as an Asgardian.
In Norse mythology, Loki is often described as a tall and lanky figure with either strawberry blonde or fiery red hair. He is also sometimes depicted as having cracked lips and scars on his face, in reference to his future punishment by the Aesir.
It was explained in “Thor” why he adopted Loki as a son. (SPOILERS from “Thor: Ragnarok” are below, so read at your own risk!) Loki was a helpless baby left to die in the cold, harsh environment of Jötunheim. Odin took pity on him and rescued him.
Offering the God of Mischief dominion over his brother's favorite realm Earth, Thanos requested the Tesseract in return. Gifted with a Scepter that acted as a mind control device, Loki would be able to influence others.
Atreus and Loki have always been one in the same character in God of War, but the name has far less significance to both Kratos and Atreus than it does to the audience. Loki, as it was revealed, was the name that Kratos' wife, Faye, wanted to give Atreus when he was born.
Loki made his debut in the MCU way back in 2011 and has been a mainstay in the universe for a decade, and yet fans are only finding out now that he is bisexual. Loki is not the first queer character in the MCU and he won't be the last. Marvel has plans to introduce a gay superhero in a film this year.
Loki Laufeyson, known by adoption as Loki Odinson and by his title as the God of Mischief, is a fictional character portrayed by Tom Hiddleston in the Marvel Cinematic Universe (MCU) media franchise, based on the Marvel Comics character of the same name and the Norse mythological god of the same name.
Loki is trickster god causes lots mischief in Norse mythology. He is one of the most well-known gods of Norse mythology. He is at least half-giant; but some report him as being a full-grown giant. Loki's father was Fárbauti and his mother was Laufey.
Frigga never taught Thor magic because he inherited his father's incredible strength so he didn't need magic to defend himself. Thor relies on brute strength whereas Loki relies on tricks and mental manipulations to defeat his foes.
In modern literature (such as Marvel Comics) it has become popular to portray Loki as the adopted son of Odin. This however has no basis in Norse mythology, where Loki is portrayed as the blood brother of Odin.
Most Marvel fans think that Odin favors Thor over Loki because the former is his natural son, while Loki is the adopted son of the giant Laufey. However, there is another, much deeper reason for Odin's favoritism, and it hides in the one-eyed god's past and his relationship with his brother Cul, the God of Fear.
The majority of storylines surrounding Loki in the Marvel Cinematic Universe had to do with his father issues. He was always insecure over how Odin didn't love him as much as he did Thor, with this eventually morphing into contempt for his father.
At the end of Thor, Loki knows the truth, and Frigga knows that Loki knows, but at no point does Thor find out the whole truth. In The Avengers, Thor says "He is adopted," so he must have learned the truth sometime between the events depicted onscreen.
After a discussion on the matter, while parts of Loki clearly belonged to the head or the neck, neither side could agree exactly where one ended and the other began. Loki kept his head indefinitely, although his lips were stitched shut as punishment for getting out of the bet with tricky wordplay.
His character also appeared in an opera cycle called Ring of the Nibelung by Richard Wagner. Later he was featured in various television series, films, video games, and, more notably, in America's Marvel comics as Loki Laufeyson. In the comics, he is based on the original Norse god Loki, the Asgardian God of Mischief.
Why did Loki turn into a woman? In the comics, Loki is reborn as a woman, known simply as Lady Loki, after the events of Ragnarok in Asgard, but even that wasn't too innocent: When Thor and his fellow Asgardians are to be reborn in new bodies on Earth, Loki actually stole the body intended to be for Sif.
In AVENGERS & X-MEN: AXIS (2014) #9, Loki found himself in the unfamiliar role as the hero when he confronted the inverted “evil” Thor on the moon. This version of Loki was so pure of heart that he was able to pick up Mjolnir and transform into a version of Thor.
In The Avengers, Loki tried to mind-control both Hawkeye and Iron Man, but while he succeeded with Hawkeye, his attempts failed on Iron Man due to his arc reactor. Iron Man's arc reactor protected him from Loki's scepter, as the scepter needed to touch organic matter to work, and the arc reactor was not skin.
The character Loki was first introduced in Timely Comics - which later became Marvel - in 1949 in Venus #6. Loki's greatest weakness is water and his spells do not work in water.
