Same colour. You want a "wood look" floor to look as close as possible to the original "idea" = wood flooring. Find a grout that matches the majority of the background colour and work with it. You don't want the grout to stand out in anyway.

Do you have a suggestion for a rectified soft grey color plank tile for a beach cottage? I am in Florida and having a difficult time finding one that is porcelain and rectified in 6 - 8" x 24 for about 1200 sq ft.
