FJ5 was part of Chrysler's 1970 high-impact paint program — vivid colors with names that shouted, designed to read at a stoplight. Like the rest of the high-impact set (Plum Crazy / In-Violet, HEMI Orange / TorRed, Go Mango / Vitamin C, Top Banana / Lemon Twist, Sassy Grass / Green Go, Panther Pink / Moulin Rouge), FJ5 carried different names on each marque's literature: Sublime on Dodge build sheets and dealer fact data, Limelight on Plymouth's. Same paint formulation; two divisional marketing words.
FJ5 is often confused with FJ6 (Sassy Grass / Green Go), which is a deeper saturated green introduced the same year. In person, the two read as different colors entirely — FJ5 luminous and citrus, FJ6 closer to a clean meadow green. The Dodge Garage retrospective on the high-impact program is a reliable reference for both naming and visual differentiation.
