Parent color would help a lot but my filly looks a lot like her and i've had a lot of people tell me she's a chocolate silver....I think she looks like a chocolate silver to me, silver bay's usually have a more reddish tint to them and darker legs I thought?
I have to go with the Chocolate Palomino because if you look closely her mane and tail would be very white if they were clean. If not then I'd say Chocolate Silver, however I'm not really a color person soooooo
