I think it's what they call Midnight Blue, which has a bit of sparkle to it too.
The person who had it before fitted a Zero-Mod thumbrest, which is only "zero-mod" if the instrument already had two holes in it for a pickguard.
As it is, the two holes are the white dots you can see in the picture and they need tidying up.
Then I got to thinking about a refin and thought duotone/flip-flop/chameleon/iridescent paint might look good; pretty much replicating and enhancing the shadow effect in the photo...
