I would lean towards orange colored if on a Cast iron intake engine.
On the majority of the BB solid lifter/Aluminum intake engines,they would appear to be natural colored,not painted orange.
But I wouldn't put that in stone,as some BB unrestored solid lifter cars have been seen with orange painted pull hooks on their aluminum intakes,so maybe some Cast iron intake engines received natural hooks as well.
Human beings built them..
