The AMT kit lists all possible factory color combinations for a 49 Mercury Coupe, including few two-tone variants. The problem is, that it does not show exactly what parts of car should be painted one color and what parts should be painted the other one. And I am unable to google any pictures, that would show the stock version with two tone. Even the original 1949 brochures show only single color versions. Could anybody help with a picture or blueprint?
I want to say that the color breaks were at the bottom of the A-posts, around the base of the top, where it met the beltline and tulip panel, and following the drain moldings that go up and over the quarter windows and doors, but I might be a bit incorrect there.
For a really definitive answer, you might log on to the website of AACA (Antique Automobile Club Of America). AACA's forums have one that covers the era of Merc's you are asking about. Now you will have to sign up as a member of the forums (it's totally free of charge, and easy to do--so do that with no worry!), and once you've been accepted (which is as close to instantaneous as instantaneous gets, BTW), scroll down to the appropriate topic area for your Mercury. Ask the very same question there, and I would bet that within 24-48 hours, someone will give you the correct answer! I've used AACA's forums for asking questions regarding several model car projects I was building--most helpful they are!
Something to consider here: Ford Motor Company, as with the likes of GM and Chrysler, had a pattern, from the early 30's until about 1950, of introducing what were called "spring colors", meaning that they came out at about the midpoint of the model year. Those colors may show up on autocolorlibrary.com.
