the flat green was painted on the bottom side to reduce glare. not sure if there is a spec for the paint color, but if there is an area on your visor (under the panel in the center) that has not faded, you could probably color match it from that.

as far as the clips. they were missing when i first got my visor too so i just made a simple set out of some metal strap material with the intention of tracking down the real thing later. never did come across a source for them but i managed to get a set off of a donor visor. that may be your best option for finding some too.
