Favored color

A favored color was a minor manifestation of a deity.

Description
Deities could show their powers through major manifestations and minor manifestations. The favored color fell into the latter category.

Most deities had some kind of color as their favored color. It was considered a minor and subtle manifestation but it was also the most frequent. For example, Silvanus could turn a tree into brilliant green to inform a fugitive follower a good escape route.

Mortals' Reaction
Followers of a particular deity often dressed in the favored color, particularly the clerics. For example, some Vhaeraunite drow took their devotion too far and blew their cover by wearing black clothes.
