I need your input and experience with grout color for this tiny bathroom floor. The floor has hex tiles of three shades, which are pretty close in color. We are trying to minimize contrast because the room is small. Of course, we don't want the grout to look worn and dirty quickly either.

First question: in your experience with CUSTOM's "natural gray" and "driftwood," do either show a lot of dirt or wear poorly?

And do you have a color preference here? The photo above is so washed out it doesn't show that those are three different colored tiles.

See?

Here they are side by side with the grout swapped out:

The one above has driftwood in place on the groutline. For comparison below, natural gray is in the same place on the groutline.

Now here are those two grouts again in one frame, at night with a flash... pretty different.

For the rest of the room we will probably do this:

Walls (Rectangular tiles): "driftwood" from Custom

Ceiling of shower (Whiter Hex tiles, not present in floor): "bleached" wood from Custom.

This will show you what I mean:

In this last photos the top color is driftwood (darker) and the bottom color is bleached wood (lighter.) I'm not trying to be confusing, but driftwood is the lighter of the two floor grout choices we are considering.

Thanks for you help! I can really use it!!!
