1969 Plymouth # 99 "spring? green metallic"
-- PPG paint code # 44032
1969 Dodge # F6 "bright green metallic"
-- PPG paint code # 2103

Spring Green was a mid year release and was coded 99, 97 or 97E depending on plant and time of year. Any non standard color, that is a color that was not specifically released for that particular make and model or cars that required special painting schemes, like a cop car, will code 99 (1969 code number).

There were some colors that received special coding such as Spring Green. Early on, it appears Spring Green was coded 99. All three plants used 99, 97 or 97E depending on the plant or time of year. Bahama Yellow coded 99 early in the year then later it codes 96. LA tended to stick with the 99 code while Lynch rd plants and ST Louis used 97 or 96 for Green and Yellow/Butterscotch.

Controversy The Fact: Code F6, Bright Green Metallic for Dodge A- and B-Bodies was first mentioned in TSB D69-23-9, dated November 27, 1968. Some sources claimed that Code 97 Rallye Green is also F6 Bright Green Metallic, but the PPG/Ditzler paint numbers are different: 2103 (F6-Bright Green Metallic) and 44032 (97-Rallye Green). The numbers from Ditzler prove that Rallye Green and Bright Green Metallic were different. Additionally, a Chrysler-issued bulletin dated January 22, 1969, listed Ditzler #43898-Rallye Green for '69 Plymouth B-Bodies (Code 99). This is the same number as the catalogued '68 Chevrolet color of Rallye Green Metallic!
As it turns out, through 1968 Ditzler used a five-digit number to identify paint colors. Typically, Ditzler used the numeral "4" as a prefix for green hues. Beginning in 1969, Ditzler went to a four-digit numbering system; however, some five-digit catalog numbers were carried over. The catalog number "2103"-for F6 Bright Green Metallic-was issued during the '69 model year-and no sooner-for '69 Dodge A- and B-Bodies. The code "44032"-Code 97 Rallye Green-was the highest five digit number Ditzler issued for passenger car applications. It was assigned to give Chrysler a specific factory application number in the Ditzler paint books. Ditzler code "43898" is currently cataloged for '68-'69 Chevrolets only.
The actual formula used to create Rallye Green for Plymouth in 1969 was the same formula used for the 1968 Chevrolet-Rallye Green Metallic.
This was not the only time a Chrysler product wore General Motors paint-the '70 Chrysler 300-Hurst's Sauterne Gold Iridescent accents were taken from the '70 Cadillac palette.
