That's my (former) car!
Jeff,
The photo you posted is of my X back in 2002 in Canberra. IMHO the colour green was the best I have ever seen, but it was not standard.
The original colour was, I believe, 390 Verde Metallic, but before I bought the car, it had been painted a slightly more vibrant green. You can see the difference in this photo...
I was sending the car to the repairers because my son had given the front left corner a biff into a bus, so I had the whole thing painted because, as you can see, a PO had it painted with bumpers, etc, STILL ON!!!
The spray painter (a friend of mine) didn't use the Fiat colour, but mixed up a colour close to what was already on the car and I was very happy with the result.
Here's some more shots including a good close-up just after it got back from the shop (but under artificial fluorescent light).
It turned heads wherever it went.
