I think it is either or both in most cases.

It doesn't even have to be a clear relationship with a colour. For example, Cardin is for cardinal, a shade of red, but more directly is associated with the Jeanne d'Arc mythos. Another good example is Glynda, whose connection with 'white' comes indirectly from Glynda being the Good Witch of the North in the Oz stories.
