So, I downloaded a free app called What a Color, that enables you to analyze any photo in your library, more or less pixel by pixel, with a matching paint color that they will help you buy. Many of the names are silly but there are literally hundreds of color names per photograph. It would be easy to pick out a few useful ones to use in a description.
For instance, I analyzed Vampire Slayer and got something like this from this photo.
Tangerine throat, blending out to saffron, with a light coral watermark. Petals are a blend of light coral and raspberry. Prominent teeth on the edge are a peachy yellow with ivory tips.
