Actually, I'm leaving the chrome on, no matter what else I do. It wouldn't be an N-1 without it. However, it is purley decorative:
"The sleek N-1 exemplifies the best elements of Naboo design. The craft
is aesthetically sound, adhering to the Naboo's love of curves and
aerodynamic shapes. A chromium finish on the front end of the vehicle
gleams in the sunlight during parades and celebratory fly-bys. The
chromium is purely decorative and reserved for starships assigned to
the Royal House." - - Galactic Voyage
Without scratch building an entire undercarriage, though, I don't think the N-1 will make much of a shelf sitter. In all the pictures of them in the Theed hangar, the tip of their "rat tail" is plugged in to a power/data interface unit in the hangar wall; the ship itself hangs in wall mounted racks.
Here is a view of the coupling/interface unit:
And a view of the hangar space, with N-1's along the walls in alcoves:
It is also highly unlikely that the N-1 would be found, "recycled," on other worlds, making the whole notion of re-paint schemes pretty much out:
"The small, sleek, fast and agile N-1 is only found on Naboo and is rarely seen even there. The fighter's compact hyperdrive allows it to serve as the Queen's Honour Guard on visits to other planets, but..., it is fragile and there is little it can do compared to purely combat craft which are dedicated for warfare."
I did find reference to a plot wherein some N-1's were to be stolen from the Theed Palace Spaceworks and sold, on the black market - but the plot was foiled and the conspirators killed. The consensus is that nowhere are they considered something to be seen except on Naboo, as part of the Queens Royal guard Regiments. The yellow paint scheme is primary to this role. So, yellow it will be.
P.S The blue N-1 mentioned above was actually an atmospheric police cruiser, the X-1. It is the primary training vehicle for pilots destined to serve the Queen as Royal Guard. The X-1 lacked the hyperdrive systems and some of the more advanced features of the N-1, but most significantly, it also was configured with a third subspace drive engine. Without some serious scratch building, it is pretty much out as a candidate.
