Initial hit came up with
16-4529 TPX
(Cyan blue)
Pretty close but needs to be lighter. Interesting to see over the chrome, reason I'm thinking a darker tint may be needed to achieve that traditional Bianchi color.
Here's a sampling color chart

As for chromovelato in light blues, have seen online a pretty Pinarello and Masi. Confident celeste can be done.
