Grout colour - limestone tiles with slate mosaics

[crazydiamond]

Hello all,

I am after some advice on what grout colour to choose. The bathroom has large limestone tiles which have been grouted with a jasmine colour to match. It also however has two strips of slate mosaic - one behind the shower head running to the floor and one behind the taps for the sinks.

I am wondering whether it would look better using a greyish grout on the slate or just continuing the jasmine which was used for the limestone. What does everyone think?

I think to continue, the light grout will highlight the slate..
