FM3 is called "Moulin Rouge" (Plymouth) and "Panther Pink" (Dodge) .
While it was technically a 1970-only colour , there are two 1971 Dodges which were factory-painted in "FM3" ; however , the documented 1971 Charger R/T has a paint code of "147" on its fender tag , as opposed to the de rigure "999" (Special Order Paint) . As to why it was assigned a seemingly arbitrary paint code is anyone's guess ...
The other 1971 Dodge which I personally encountered was , prima fascia , Panther Pink . It was on a 1971 Challenger R/T ( 300hp 383 Magnum , 4 speed , Super Performance Axle Package ( 3.91 / Sure Grip , H.D. Cooling w/ clutch fan and some other specific parts) , W11 Deluxe Wheel Covers , black interior , AM-8 Track 5 speaker stereo , rear defogger , etc.
Its paint code was "999" , which lent some credence to its Panther Pink paint . A subsequent search for the cars build sheet(s) turned up nothing more than a shreaded-remaineder ; and under "comments" , handwritten in grease pencil , was "GB8" (another factory colour , but was limited to C-bodies)
"999" simply means that a customer ordered a paint which wasn't *available* on that specific car line (i.e. , EA9 Charcoal Ird .on their 1970 Challenger . Since 'EA9' wasn't listed as available for any carline except the Imperial / Monaco / Fury , the Challenger received the Special Order Paint "999" code. ) or was a limited-availability colour ( "Rallye Green" on the 1969 B-bodies , which was shared with Chevrolet's car line (e.g. , 1969 Camaro) ) .
