FY1 is the high-impact yellow in the 1970 Chrysler high-impact program. Plymouth's 'Lemon Twist' is the name that carried in collector usage; Dodge marketed the same paint as 'Top Banana' per the Dodge Garage retrospective on the program. The 1971 carryover code is GY8, with Plymouth renaming the color 'Curious Yellow' on its fact-data; Dodge kept the Top Banana name.
