So which characteristics do you describe when you're asked to describe a person? Which features do you imagine? The shape of their head?

I would assume that most people have some form of non-visual, database-like memory for each person.

(I sometimes lose the ability to recognize people when they change their haircut, when they wear a different type of clothes, or when they meet me in an unfamiliar setting.)

Tall, round face, short hair, wearing glasses, with mustache and beard, thick eyebrows. There are still plenty of ways to describe someone's face without using colors, but to be perfectly honest I'm terrible at describing people I can easily recognize.
