I am installing medium sized black hexagons on my bathroom floor with charcoal grout. My mudset shower floor will also be black hexagons, but they will be small. The shower glass is clear so you will see both flooring. Should the grout on my main flooring match the grout on the shower floor? I was thinking of doing silverado in with the shower floor, should I be doing charcoal grout there too?

I'm doing white subway tiles in a herringbone pattern with silverado grout on the walls. This picture isn't mine, but wanted to show for inspiration.
