This is a better picture of something very similar, probably the same - but mine are closer to 1-inch tiles.

Here is a link that might be useful: Alloy Deco Chalkboard

Hoping someone sees this. Just about everything I've learned about kitchens has been thanks to you all on these forums.

Thanks!

I used a mosaic with frosted glass, shiny glass, stone and stainless. I saw the mosaic with light color grout that matched the stone pieces but I ended up going with a very dark green grout that matched the darkest glass pieces. I think the light grout made you see the grout too much and also made the overall look too busy. With the light grout you see the individual pieces rather than the whole picture. The dark grout disappears and you don't really notice it at all.
Just to show you what I mean I am posting a couple pictures

This is a shot of my installed tile

And here is website picture of the same tile with light grout

If you are using a professional tiler to do the install he should have grout samples to show you. If you are doing it your self take a sheet of the mosaic to a tile store and ask to see their grout sample pieces. Look at the samples against the different color tiles. If you can't decide that way, you may have to buy a couple colors of grout and and actually grout small sections of one of your sheets of tile with the possible grout colors.

Good luck

Thank you so much, badgergal!!

Exactly what I needed to see.

I would use silver grout (just like in the picture). I just like the way it looks with the tile.
