I think I'll get a strange mint sensation looking at 229's robot!
The anodizing looks good. The green and yellow makes a good contrast.
At work when we do toolings for our injection molding robots we've run across the same problem where the color varies depending on the material used to make the individual parts. We do a clear anodize to prevent this unless specified by the customer and at that point we just say the toolings have "character".
