All purple sections were repainted in a slightly darker purple, all grey sections were painted silver, all black sections were painted in a dark mix of silver and black, and all yellow sections were painted in gold and then covered in a custom mix of Tamiya clear yellow and red for a metallic orange look. I then added tiny bits of silver to the edges to simulate a worn and grimy look.
