ah ha! something I can actually help with!
I have a black safari tank on hand and it will be installed on my bike after i finish a bunch of other work. (as you can see below, the bike is in my house and i'll wait to take off the old tank & install the new until i can at least open the windows on a nice weekend day, or just do the work outside.
so anyway, these pix probably give a decent idea of how colors play out together - even if the fit isn't right yet (read: i'll probably bolt a few things down before i ride far from home).
as i think the last photo shows, the logo is in fact printed directly on the tank (i.e. it's not a sticker) - - i think we're talking about that in another thread, yes?
i hope this helps,
paul
