help wanted with navy armsmen colourscheme

[millest]

hi folks

after managing to aquire a forgeworld pilot and a squad of cadian FW models (4 shotgus, 1 of each special, an officer, a kasrkin officer and a converted sniper) im thinking of painting the cadians up as a squad of navy arms men (a bit like his body guard) it might even end up as a diorama.

basically though im looking for suggestions as to a colourcheme to represent naval battle troopers?

any suggestions?
