Simon to my mind Deep Bronze Green would be just fine, in fact absolutely anything in DBG would be fine. I tried, without success, to get the gates & the woodwork of the house in DBG. We have an ammo box for letters on gate post, I wanted to paint it Service Brown as nature intended, but no "army paint" was allowed, it had to be bright blue. Although I had a little chuckle as this is not ordinary blue, this is French Blue H1/8010-99-220-2329. As Fletcher said, little victories!
