my cars paint is like that too...
On a sunny day when parked uncover (how I viewed it).. it looks black with shiny silver bits..when outside.. black with a golden haze (also how saw when bought...) gorgeous..
It also looks black/silvery/sparkly at night when clean..
The rest of the year the car looks like an off black/super dark grey..
when you look close the paint is black with silvery flecks.
