what colour should they be, just a light green?
Yeah, that emerald/Brunswick colour might have been too vivid for it, actually...might have looked better a lighter more subdued green..
Bit like the people who mistakenly go around spraying all old Holden sixes Chevy Orange or even Rocket Red is not correct for all of them, there was a third correct colour that most 173s and 202s and a lot of 253s and 308s were actually painted, a pale pinkish orange,not as wild as Chevy Orange, and it never seems to have come out in engine-paint spray packs or whatever..
