Amber is always an overweight girl with brown hair who is really into niche hobbies. That's what I envision. I want to like the name because it does sound really warm but I can't rid myself of the Ambers I have known.
I would pair it with an equally warm name but not of the same initial because I don't like alliterative names as they sound cartoony to me. Maybe
Amber Harriet,
Amber Helena,
Amber Medina,
Amber Mallory,
Amber Rosamund,
Amber Melisandre,
Amber Romana?
