Are you looking to paint the rams head black and the background a different collor? Timmy916 (i believe is his name, i know its 916 lol) has a good writeup about painting the emblems.
As far as paint used most guys just use plastidip for the ram/grill and the colormatch spray cans available at your local autoparts store for the background (the grill RAM head comes apart and allows for easy painting)
