Grout help - I’m using Castelli tumble marble Bianco and Durango 4x4 in a diamond pattern for the bathroom floor with Cle tile’s terracotta white baguette shaped tiles in a vertical stack for the bath surround…

I’m SO lost with grout picks. I want to pay homage to the warm “Durango” of the floor tile in the bath surround, but don’t want to contrast the grout - would like a soft look.

Then for the floor, I feel a white thin grout would work best, but all the whites im finding look very bright? and then they get dirty?

ive also read I should go unsanded but that fine aggregate like permacolor or mapei FA should be fine and I plan to seal before and after too

I’ve considered largely mapei colors like alabaster biscuit avalanche light almond and eggshell … help this indecisive homeowner 🥴
