It looks Pewter in this photo. I would say though, that Pewter, Willow and sometimes Indigo do tend to be difficult to discern in photos, they seem to "pick up" surrounding colours from other objects or fabrics nearby. I have a Willow vase which I tried to picture accurately on numerous occasions and nearly all the results make it look Pewter! I know that is not much help to you but
they are (to me at least) fairly obvious in the flesh! Just in photos are tricky. Will try a photo later for you.
