How did Gandalf's gray wizard upgrade to a white robe?

Because he killed Everett, the wizard's rank was improved and the color of his robe changed. In the Lord of the Rings world, the color of robes represents the rank of wizards, and white robes and gray robes are no exception. It should be noted that the level here is not based on mana.

Saruman in white is the highest rank among wizards, while Gandalf in gray is the lowest rank and position. Therefore, Saruman can talk about world affairs on an equal footing with Elf King and others, while Gandalf in gray is more like an errand boy, although he maintains the friendship of all.

Gandalf is tired of power and keen on adventure, so he is willing to be a wizard in gray. Compared with Gandalf, Saruman, who is keen on juggling various rights, is indeed more suitable for the position of white wizard.

Role background:

Gandalf appeared as an old man. He has profound wisdom and likes smoking a pipe. He has a gray beard, a gray cloak (probably corresponding to the name of Gandalf, a gray wizard), a gray-blue pointed hat and a rough wooden crutch.

Bilbo baggins described him like this: "An old man on crutches. He is wearing a blue pointed hat, a gray cloak, a silver scarf, a white beard and heavy black boots. "

Although some people know his essence, others mistakenly think that he is just an ordinary magician. When he first came to Alda, people thought he was human until people found out that he could live forever. Later, some people thought that Gandalf was an elf, but he was completely different from the elf, because the elf could always be young, and Gandalf always looked like an old man.
