White or limestone roof (the limestone seems to fade to near white in time) and bronze green. My ex-mil is bronze green overpainted with drab olive (by the army) then touched up with NATO green (by me because I had some). The bronze green is the nicest of the greens and it is the colour of the interior as the army only slapped paint on the outside. Cappings are tricky, if its ex-mil then they pained over all the bright work (my cappings and screen are black) but for civvy then galv looks nice but galv paint can be too shiny so some people mix a shade like weathered galv. As my cappings are black I will probably overpaint them in green when I do the whole thing in bronze green over the next few months. I'll mini-roller it on. The military do have green tops but they look very drab, which of course is their intention. I recently painted my wheels limestone (well Wilko "almond") which is very wrong for an ex-mil but it looks really nice and sets off the green.
