Colour matching on screen is always a bit of a mug's game, but take a look at Bob Jackson's colour samples at http://www.bobjacksoncycles.co.uk/frame-resprays/ - metallics and flamboyants are the ones you'll want to examine. Flamboyants are translucent colour coats over a metallic silver or gold base coat; they tend to have greater depth than plain metallics, but are significantly more fragile.
Looks like they just added a lot of glitter to the clear coat.
