What about neon pink, tye-dye and green circus colors? I'm sure many pirates weren't too big on the conservative ConFleet paintjob and were at liberty to paint their own fighters. You can have some logo on the fighter too, to designate their pirate clan. For example, some clan called the Cherry Busters you can have some sort of boot kicking either a fruit cherry or some female . . . um . . . "biological asset".
