Not sure, it is nice though! I don't know if you will find a satin color like that on GT5 though? Than blue almost looks like the Plasti-Coat blue you can buy for your rims etc (in real life)
Thanks guys, I tried aruba blue and phoenix blue but they were a bit off. I might try champion blue though, thanks for the help

Overall, I would say Aruba Blue is my best option. Thanks everyone for their input.
