I'm not sure if this has been pointed out before, but I have repeatedly noticed that Elhan's hair changes colour during the game.
Outside Suldanessalar, his hair is grey whereas in Suldanessalar his hair is ginger.
Has anyone else noticed this, is this some sort of bug, or is this intentional for some reason I have not discovered.

I have noticed this too; the same thing happened to other NPC's such as Terl, a man who *tells stuff* to Anomen... I think the game creates new copies and it makes mistakes.

Probably just *had* to get his hair dyed on the way over.

Yeah, you know about elves and their vanity...

Here I have clear visual proof (admittedly these are Icewindgate screenshots):

Probably Bioware just assigned 2 different colors of hair by accident, one for the Suldanesselar one, another for the Underdark Exit one.

you know how peoples hair goes grey with stress? maybe elves hair goes orange with stress...
