I had a small workspace, so I had to paint in small batches.
So I painted the colors of the parts with the least number of parts first.
Matt black, Matt aluminium, Chrome, Stainless silver, Gunmetal, Copper.
Now it's time to paint the main color, blue.
I decided to do a two-tone color scheme, so I made a light blue(R) and a dark blue (C).
The left color is failed, because too low saturated.
