the list done by Willie is good to have but I'm surprised that Giallo Ocra and the Francia Blue AR342 for the 1750GTV models are not listed. I believe these were very popular colours offered on the US models.

I would have to agree with Damo105, Blue Francia (AR342) is a deeper blue and darker shade (I would post a picture of my car but most of the top side of the car had the enamel "sun burnt" off down to red factory primer). Also, I don't see the so-called "Azzuro Le-Mans" listed on the Bertone colour code list posted by Krister.
Theese cars are soooo beautiful! I love that color, Le Mans Blue, can't wait to see one IRL. Mine was originally Rosso Alfa 501 and I wanted a red one so when it got new paint 501 was the obvious choice.
My top 5 color list
1. AR-501 Rosso Alfa (You got to have at least one)
2. AR-348 Le Mans Blue
3. AR-109 Giallo Ocra
4. AR-216 VerdePino
5. AR-213 Verde Oliva Metallica (Not sure I've seen a 105 with this one)
