No I am not. I have seen a st185 in that blue, and I am not a huge fan of it, though that 185 had headlight conversion and no rear spoiler. It was ok, but I was not feeling that color.

Super White 2 040
Silver Metallic Clearcoat (Cladding Color) 181

There may be more than this.
Custom colors I have seen off the top of my head:
Flat black, various silvers, custom reds, lime green, primer, yellow, various oranges, blues, pink...
I am sure there are more, but out of all the ones I have ever seen, I have not seen this paint code used.
