In "The Lord of the Rings", the difference between white robes and gray robes:

1. In the wizard level, white robes are one level higher than gray robes.

2. In terms of spell ability, white robes are stronger than gray robes.

3. In terms of personality, white robes are more cautious and serious, while gray robes are relatively casual and free-spirited.

4. The white robe is the head of the wizards and is more refined.

According to the setting in "The Lord of the Rings", wizards have four levels: white robe, gray robe, brown robe, and blue robe; one person each in white robe, gray robe, and brown robe, and two in blue robe.

The original white robe was Saruman, the gray robe was Gandalf, the brown robe was Radagast, and the blue robe was Alatar (Morinehtar). Moreda) and Pallando (Rómestámo Romesdano). These five wizards are known as the "Five Wizards of the Ring."

The white-robed Saruman later rebelled and turned into a colorful robe. Sometimes he turned into one color, and then into another color. Even the gray-robed Gandalf called him a "chameleon". Gandalf the Gray was killed in the battle with the Balrogs, but was later reborn and upgraded to Gandalf the White.
