I got my hands on the MG ν Gundam that was re-released in April and diligently worked on a full paint job on my days off.
The internal frame is basically Starblast Iron, the ducts are Starblast Gold, the cylinders are Clear Gold ball joints, the parts that are partially visible are Starbright Duralumin, and the psychoframe is painted Metallic Green and Tourmaline Green.
The white exterior is EX White and Moonstone Pearl.
The navy blue is Prism Blue Black.
The yellow parts are Clear Yellow Candy.
