Well, 'all you know' is pretty much it. She's is indeed a Cinnamon Violet. To flesh it out a bit more, she appears to be a Single Factor Violet Cobalt Cinnamon. Cinnamon mutation dilutes body color by about 15% so whether she's single or double factor violet may be an open question. Do you know anything about her parents? That could be determinative regarding that question.
BTW, her chewing on the holiday lights makes me nervous.
