Never seen it... I assume it wasn't offered in the US (car is in France):
Thanks for the chart! Very informative.i have it in my dupont color charts. there was a lighter blue as well.
There were several different colors for Europe.Per the sales brochure, the S4 spiders only came in black, white, silver, red, green, and yellow. Unless they had other color options in Europe looks like it's aftermarket.
