Get a sample of the white.

I do not love cherboard floors and without a lot more info why these tiles at all for that look? Please tellme not in a kitchen. If in the bathroom IMO a lot simpler tile is best for a classic timelss choice . So some info as to where and pics of the cabinets please .I will say I do not like either combo .

Dover White is very creamy with yellow undertones and the tile seems much cooler. And the tiles are warm and cool next to each other.

A color somewhere to tie warm and cool tones together, see how the door in dani's first photo works, like for the walls maybe.

If there is white in the room, the white might look good with the taupe, otherwise white would be too bright. In that case you could do white walls.

I would choose the lighter of the two. On the diagonal.

I lived with black and white checkerboard floors in an old house in Boston - oof, they were hard to keep clean: dark debris showed on the white tile and light debris like dust showed on the black tile (I felt like I was cleaning them all the time, waaaay more than my current hardwood) - if I were to do checkerboard again, I’d go lower contrast like what @dani_m08 is showing

cabinets have been ordered, want a tile look but not ceramic, I live in the NW

You might like the large format limestone look https://www.houzz.com/discussions/6061284/seeking-help-sourcing-large-format-limestone-look-tile#n=257

You have still not told us what space .

The light gray and taupe is fresh and contemporary...looks great with your samples. The gray is the outlier so you need gray or black in the room or even stainless steel for it.

I assume it's the kitchen.

so sorry, kitchen floor, I love the limestone look someone mentioned, but I couldn't find anything creamy enough for the dover white and my whole house is creamy, living in the NW everything is naturally grey, so don't want to add to it

- are you wanting a light colored tile floor with dover white cabs? Totally personal opinion but i’d go hardwood or classic slate floors with white painted cabs (I think the cabs need some contrast to shine but that’s just a me thing) FWIW we also have dover white cabs, but med hardwoods

I don’t love tile floors but there are some really pretty Ostuni tiles in that thread, lots of lighter options

I love the floor in the above photo!

I think that I would do the gray and light taupe ones - they will provide a "soft" look - obviously not the same as real limestone as above - but still that softness.

You will need to bring the gray into the kitchen - I'm hoping that it is a warm gray which would allow you to do a really soft griege shade on the walls? Maybe you could bring in some of those old/homemade looking cement planters/bowls or something to use as accents?

RH - but there are many youtube videos on how to make them diy:

Cement/concrete orbs are made in all different sizes/styles + can be used inside as well as outside in the garden. Most are solid cement/concrete - however, this woman (Barb - "Made by Barb.com) makes all different types:

Amazon had large cement lazy susans - in various sizes - which could be used on your kitchen table:

You could also have a concrete dining table in your kitchen. There are many sizes/shapes. This one is from Etsy:

This is a quartz top table with acacia legs. It comes in two longer lengths than the one shown below (Wayfair):

This is what the top looks like:

There are MANY ways to introduce some gray color in your kitchen to coordinate with the floors if you select to do a checkerboard floor with the gray and taupe tiles.
