Can I see a close up of those tiles and also the reason for that color. They look really busy/ reflective on my screen which I do not find attractive in the space .

Apologies... mocked-up with tile still in wrapping. Other elements with olive/apple green in the open plan.

You could do a custom one that matches the tile or an alabaster color.

Thanks! Had another vote for white, thought it could get dirty fast... but from other remarks in this forum, choosing something that hides dirt often ends up looking pre-dirtied.

IMO the best grout for glass tile is as close to the tile color as possible.IMO whaite is never a good choice for tile in a kitchen.
