Here’s a Question I Haven’t Seen On a Mopar Board Yet (Re: Alpine White)

EW1 is the code for Spinnaker or Eggshell White.

1969 Chrysler Spinnaker White paint
This white automotive paint color is most commonly known as simply 'White'. Other common color promotional names include Spinnaker White, Spinnake White, Eggshell White, Alpine White, Dover White, Eggshell, and Tractor White. The color formulation has been used between 1967 and 1983, primarily by Dodge; but also by Plymouth, Chrysler, and Gravely. We have records of this color appearing on the following models: Dodge, Plymouth, Fury, Dodge Truck, Imperial, Coronet, Valiant, Dart, Monaco, Polara, Barracuda, Charger, Challenger, Satellite, Belvedere, and Chrysler Special Order / Fleet. See the full detailed list below.

The short model/year code for this paint in 1969, is W1. The longer Chrysler paint manufacturing code, sometimes called the "Dodge Truck paint code" is DT1417. This longer manufacturing code is useful for tracking paint usage
