Silicone Silver is a special colour (that is why is more expensive). I had F-Pace in that colour, and it looks great with black pack option. What is funny with this colour, depending on the surroundings colours, it is changing its colour as well, so it is different in the morning, noon and evening. See enclosed pictures.
BTW, I-Pace in that colour looks awesome! Especially on the black and silver alloys!
