[Legolas]

I posted this in another thread...

White was the colour chosen by Saruman, and because he was held as the chief of the order, Gandalf took over that colour when he returned and Saruman's direction had gone ill. The other colours are not related to the stature of the corresponding wizard. They do seem to say a bit about that wizard's character, however. Brown is associated with the earth - Radagast was in love with nature, as 'his' Vala was (Yavanna). Grey is generally considered not so appealing to the eye, much like the rest of Gandalf's appearance. The grey only furthered the masking of his great power inside and was a reflection of his humble spirit. Not as much can be said about the light [sea] blue that Alatar and Pallando wore, except for that it suggests that they were definitely different...throughout the rest of the story, we just see characters wearing green, brown, grey, etc. - nothing particularly eye-catching.
