I don't think you'll get what you want in a shaker can mix. the original color was a tricoat paint meaning, a silver metallic base coat, followed with a candy color and then a 2K clear coat.
My personal preference was going with Hose of Kolor Silver Orion Max base coat, followed with in my case Brandywine candy and then 2 K clear coat. Branywine is almost a dead ringer for Honda's Candy Glory Red which is what I want my bike to look like. I bought the paint and have been sitting on it due to "other" life commitments holding me back. But for the record the House of Kolor paint cost me $670 CDN and it's probably enough to do 2 bikes with since I had to buy a liter of each plus a liter of 2K primer.
Just a quick look of the House of Kolor paint chart , I think this cobalt blue would be pretty close.

and I would change out the base to Orion Silver Max. The flip flop of the metallic is absolutely amazing.
