She is still changing but her back looks like it is a dark blue... and gold in the front.
She is not done changing, usually the silver on the head will clear out and be more gold or tan. and her back may keep lightening up. She won't be completely done changing till she is 2-3 years old
Did you see her parents, or grandparents? sometimes that can give you an idea.
She is almost exactly the same color as my Maddie is right now, If she were older I would think that they were related
