You need to be very careful with the correct titles for these two colours....otherwise serious confussion will occur.
The pre-'67 colour is called DEEP BRONZE GREEN.
The Vietnam era colour that was superceded by the modern camoflage colour is called OLIVE DRAB.
There is a confussion built around some people referring to a bronze olive....that's a colourbond fence colour only, or the other one.....drab green or olive green, they're house paint colours not military spec. paint colours.
