My first impression of my T was if Fiona Shaw and Jody Foster had a lovechild. Her picture online shows her with light brown/reddish hair but I have always seen her with dark, straw-like hair. I think she dies it but doesn't invest too much and probably does it herself. Her voice is very down to earth but not low.

This is the closest image of Fiona Shaw I could find. The eyes and the smile are very much like hers.
