I have the Subway Ceramics Avalon / Minas with a medium gray grout. And a Shaw's white sink, if anyone is considering that, by the way. (My contractor could have ordered it directly, but at his request, I went through a tile store, and by the time everyone had put their sugar onto it, it was OBSCENELY expensive.) I'm not an installation expert, but at least with the Subway Ceramics, the installers use little plastic spacers between the tiles (I think some others have their own spacers?) when they put them up, they don't do it freehand, so how much grout you get is a function of 1) the limits set by the curvature of the tile and 2) what size spacers they use. So you might be willing to go a little darker with a smaller grout line, or with a handmade tile that refuses to go close together, you might want to stay light. The traditional color is close to concrete. But most modern people don't seem to like that, so do what pleases you!

Cream colors (most off whites fall into cream categories) and white/greys don't usually look good together. They make each other look dirty. Get a few pieces of the white marble tiles and get a door sample in your color. Bring them home to your kitchen, for your lighting, and put them next to each other and see what they look like they. If you see color like most people do, you're not going to think they look good together. Get a back splash that's warmer/beige in hue or a completely different color than white. That's just my opinion. Not written in stone.

Thanks everyone. I'm all smiley and giddy hearing your kind comments. It melts me heart. I'm glad to hear people like the backsplash tile. It is pretty bold. I was also THRILLED with how the stain on the island turned out. Interestingly, lots of people say the kitchen has a peaceful look and feel to it and that wasn't necessarily something I was aiming for but my kitchen mission statement did include "casual but sophisticated/elegant" which might boil down to "peaceful or tranquil". We feel very blessed to have been able to do such a large scale kitchen remodel and are thrilled with how everything turned out. It also means we won't be moving for the next 15+ years! I can't wait until the bar stools are in and I can start serving snacks to my kids there. We are borrowing one bar stool right now and it gets a lot of use. clarygrace and others - I'm glad to hear you think the colors are coordinate b/c I was in a quandary about that at one point. I can't wait to see your kitchen and island. We love the shape of ours but did it b/c it worked within our constraints. We didn't want to mess with the existing deck outside the bay windows and we couldn't push right much more either b/c of the powder room. And speaking of the powder room - here are pictures of that which was also part of this remodel: tea4all - the pantry is pretty small as far as walk-in pantries go. Finished dimensions are 5.5' long by 46'' wide. We weren't originally going to do a pantry but it made sense with the rest of the layout (it brought the oven closer to the rest of the kitchen) and I am really glad we did! It was actually framed larger and had to be redone b/c large aisles were more important to me than a few more inches in the pantry. The other detail I forgot to include - the grout color on the backsplash is Custom Grout Light Smoke and on the floor it is Lacrete Parchment (just in case someone really wants to know - ha!)

Here is a link to google, how that backsplash should have been installed. There are some u tube videos too. I watched one video, where they used grout, between the countertop and the backsplash, and grout should not be used there. Caulking shud be done between backsplash and countertop. My backsplash is also caulked in all the corners, rather than grouted. Once you watch these videos and read these articles, you will see that your thinset was put on improperly, and thats why your tiles are falling off.
