Is there more than one shade of grey for facelift interior plastics?

[Adrian E]

Looking to replace some bits of trim but really difficult to judge from pictures whether the colour is the same as what's already fitted in the car - is there more than 1 shade of grey that might be fitted for stuff like interior mirror (i.e. hard plastics) or door pillar trims?

I'm thinking it's highly unlikely, but does anyone know for sure?

Cheers
