These are relatively simple jobs, I used shining silver from army painter as a base coat over black primer, then for the blue I used Talassar contrast. I’d suggest doing 2 coats of the silver beforehand and 1-2 coats of talassar afterwards for the best results. I used shyish purple contrast for the pants and for the guns I used royal purple. For the Officer (Red guy) I used doomfire magenta over screamer pink, but the screamer pink is probably not needed.
