It truly is an Imperial ship: It only looks good in white. Every other paint job accentuates the awkward curves and angles it has.
Don't you think the currently available white paintjob is a bit too white, though?
In my fleet, cargo ships are always white... mostly because my Cutter is white and I didn't want to spend on a paintjob for it.
My Corsair is going to be a cargo ship (albeit, an armed/armored one) so I wanted the white paint for it but it just looks very... white.
Hopefully, FDev will eventually create "Tactical" paint for the Corsair because the "Tactical Ice" paint usually has various panels colored in black.
