"....However, I seem to recall that the red was replaced with green on the packages sometime during the war."

I think it's the other way around. Lucky Strike was originally green. During the war, the color green was needed so LS went red.

A commentary on "Madmen" is where I probably heard this.

Thank you for correcting me! That makes a LOT more sense; changing from green to red. ....I was a war baby and only about 3y/o when the war ended, so I was only recalling the phrase of LS Green going to war.
