What color would you call my kitty?

Rowan was found as a stray when I worked at a Humane Shelter. I noticed her coat was dark brown. As she got older, it started to fade to a more milk chocolate and caramel color. She has a white undercoat as well. Would you call her a chocolate smoke? I am stumped.

Do you have a few more pictures, of her in daylight? At different ages preferred. It's really hard to tell with a dark picture like this. Specially because the difference between a black and chocolate is little. For smoke I'll also need more light, to see her face better, and if possible her tail. It'd also might help to take a picture of her fur on her back brushed to 2 sides (In daylight, to see whether it's white or another color)

Thanks!
