Do you mean more TRON-like? If so, use a nice, vibrant blue like Temple Guard blue as your top highlight. I don't think you need a layer in between, but you could always try Kantor or McCragge; if nothing else, it will brighten the surface for Temple Guard, so that it doesn't have to go on as thick. To emphasize the corners or points where light hit, you can use the one from the Edge set, not sure of the name, maybe Baharroth. Or, you can always just use white.
Edit -- your pic came up after I hit post

The bad thing is, that particular color, I don't think is in the
GW range. It actually looks kind of like the Vallejo metallic blue gunmetal to me.
I think the closest
GW color might be Stegadon Scale Green or Incubi Darkness? It's also (sort of) reminds me of the P3 color, Coal Black. None are a perfect hit for that model, though that picture isn't exactly what you want anyways, so maybe it is what you are looking for
