Well, I had a look at the full tile online:

And this was the best picture I could find.

From what I see, the "value" color is the highest contrast of this style, correct? And I assume that your picture above is closer than this one I found...so basically will show as a black and white hex tile.

Now this photo above shows the tile laid in a kind of random pattern--you can see a couple of white ones next to each other and a few black ones next to each other.

An individual tile on the Emser website shows looks like this:

My thinking is that if you do it this way, it will look very polka dotty....both because of the high contrast and because of the symmetry. I'm going to go ahead and assume this is NOT what you want unless you enjoy a migraine with your coffee...

Now if you plan on having it set more random (like the tile website shows) make sure that your installer knows that...

Are you sure you want that much of a contrast, though? Especially all over that wall?

It's a lot to take in...

That website does have a "visualizer" but I'm not sure if you can download your own picture as you have to register...

I guess I wrote a lot but didn't say much :-/ However, I'm not one to discourage if it's a look you love.

ETA Wayfair sells these if you want to buy a few and try it out...
