I think the white hexagon tiles would look great!

Try an ogee or arabesque shaped tile in a soft blue or gray-green that will inject a bit of color but still be in keeping with your other selections. Will also provide a bit of visual interest to break up all the rectalinear surfaces.

It appears that the island cabinetry is gray? I would pull in the gray in the island on the backsplash.

The very right tile on the top photo looks good to me.

Perhaps a white & grey tile done in an lovely pattern - herringbone or chevron for example and use a light grey grout.

Another vote for color, maybe a pale bottle green...

So in looking at the comments, it looks like the theme of white might be too much white, right? I just see all of these beautiful primarily white kitchens that I love but I want it to look right in my space.

Stunning kitchen! I would recommend the white hexagon tiles (on the left) if you are going for a clean & timeless look. It will look very nice with the black hardware too! Post an updated pic when you're finished! So exciting!

if you want to see what the white would look like, this kitchen is almost the same as yours....

it's nice, but that white subway is so trite at this point.

Have you thought about doing cement tiles? ton's of colors/patterns. this is a bold black and white,,,but you get the idea (notice the wood beams like yours)

you could also do a herringbone pattern for a little interest. these are longer marble subway tiles (2x10 or 2x12)

you could also do a glazed brick type of subway. CleTiles, Fireclay tile, and Tilebar all make them.

CleTiles has some beautiful handmade white ones

or their Zelleige in this fish scale would look really nice w/you elements. just enough of a pale blue/gray to work w/your countertop and your island. would also compliment the wood elements beautifully.

I love the herringbone marble tiles!!!!

Beth H. our lights are the Hinkley Fulton in the pick below. I did simple black hardware but should I change to gold or do you think the black would look good if I did a marble looking backspash?

Can you mix gold and black hardware? Like black on the white cabinets and do gold on the gray? Or is that weird?

the Cle tiles in the fish scale. (love these)

it's hard to photo shop these lantern shape cement tiles,,,these would interlock w/each other,,but I like the way it looks.

also like the cement tiles. goes wonderfully w/your wood beams.

You absolutely can mix them. I'd do gold on the island and black on the white (as you say).

nice lights. If you're doing the gold lights, I would do a very soft, gold hardware. I do like the black as well, but unless you have the black in the lighting and the faucet, I think it will look a little heavy.

look at the champagne or very pale gold brass,,,

or even something like these

or do both! two tone black/gold

What exactly do you mean unless you have the black in the lighting? The lights are black iron with the brass just on the inside portion like the pic above. I have struggled to find the gold handles like that, any suggestions?

sorry devyon,,,at first glance I thought they were all brass. my bad.

then yes, you could do either. what are you doing for the faucet? Black or the gold?

There are tons of gold handles to match your lighting. They don't have to be the exact, same color. you could do a lighter gold if you prefer. What exactly are you struggling with

Well we purchased a brushed stainless faucet :( but now I am second guessing it. Our appliances are all stainless. Is that bad? I was just having a hard time finding gold bar handles at a reasonable price online.

what's reasonable? try knobs4less or something similar. you can also try AliExpress. They come straight from overseas so you can cut out the middleman and save quite a bit. I ordered my gold cabinet hardware for my closet w/them. It's the same stuff you get online through the hardware companies. There are many vendors on Ali, so shop around. some have minimums, some don't

You'll be fine with a stainless faucet. Here is black, gold and stainless mixed in a kitchen.

I think your kitchen is absolutely stunning devyon! What ever you decide will be perfect ...look how gorgeous it is already! You have impeccable taste and interior design!

What color will/are the walls painted. Grey? How much backsplash is there in the kitchen?

There is a nice feeling of continuity when the backsplash is a similar color to the walls.

I love that bottom one CR Design!

Yes.....you don't get that choppy feeling of tile vs. wall color.

Here is Repose Gray and yours is a little lighter than this at 70%, correct?

Yes!

You also will need to think about where you will be ending the tile vertically.

Is that a gray glass tile? That's what I was initially trying to go for with the subway glass we had in the first pictures but the light color came off a little green in natural light which I didn't like. The one you have above is pretty though!

That is actually a screenshot of the tile you posted above! LOL It came out as more gray in your photos. So, if you liked that, now you know you want something like it, but more gray.

Repose Gray does have green in it, so I wouldn't go too charcoal.
