Lots of striking blue's: Minerva, cobalt, riviera, Mexico, maritime.
Could also choose Toyota FJ Cruiser blue, called voodoo blue which I've seen special ordered via special wishes dept on 911's. Pulled off net, so check for correctness. You have a nice ride and the proper color will make it pop. Good luck and please share the finished product with us.
