BUT your monitor color settings may be different than mine.  What does this mean?  The colors may appear different on your monitor. 
Also, lighting affects the colors as you will see on many of the photos.

* After conversation with Gil Baumgartner, CTCI concours chairman and authenticity guide auther, who has been studying the various colors thru data plate & factory invoice information.  (Bet he would have loved to have had internet info from the 50's that we have now for the new Thunderbirds)

Note on door panels of the 57s - Lower part of panel has the Thunderbird emblem embossed throughout. Note on seat back: Middle of seat back on the very early 57s (thru Dec 56) have an embossed emblem matching the emblem in the middle of the steering wheel.  This is a popular emblem and you may find it on just about any 57 that has had seat covers replaced if it's not being shown in the "original concours" class at CTCI events.  More trivia on this embossed emblem: When originally done, this emblem was heat set into the vinyl and tore out quickly which is why FMC had it replaced with seat covers bearing no emblem for the rest of the 57 production.  A new method for embossing the emblem into vinyl appeared in the late 70s, early 80s thus this treatment to the seats became the popular choice for restorers.  C.T.C.I.'s Early Bird Magazine, January/February issue 2005 has an excellent article on the color combinations available on the 55-57 T-birds.  These include hardtop color choices & interior color choices available with the different body colors.
