Magical Aura Colors

[Yu Baka]

I remember in the novel Prince of Wolves the colors of certain schools of game gave off different colors. I was wondering if anyone had a list of what colors each of the schools of magic give off when someone is using detect magic?

I don't think anyone has defined these.

Who says they have to be colours? Its magic! Perhaps detect magic endows the caster with a new sensory capability, and the auras themselves cannot be described with mere colours.

Example:

Abjuration: Glows with the scent of fresh-baked bread. Smells red.
Necromancy: Glows with the light of B-flat. Seeing it recalls the scent of roses.

etc...

I remember the wizard describing the auras he sense as color of auras. I need to reread the passage to remember all the details.
