Some more droids from GZG, pack SQ15-V16 Humanoid Bots. I've gone for the standard gold protocol droid type colour scheme on the first two servant robots. The photograph hasn't come out particularly well, they do look a lot golder in person! I've used a dark brown base coat rather than black so that the contrast isn't so stark.
The big cargo handler droid has an industrial type yellow colour scheme. I assume you'd want it to be easy to see when it's walking around carrying large objects.
I'll be painting the duplicates in more varied colours, in particular I was thinking white/pink on the middle one for a Futurama style Fem-bot!
