Opinions on kitchen / floor tile combo

Another tip on how I’m currently setting up our new build:
Sweet Home 3D. It’s not too difficult to use even for laypeople, and you can partly insert the original furniture. And above all: the original textures of your floors/walls, if you find them online.
I saved photos of our floors from the manufacturer’s website, clicked together a very cheap laying pattern in Paint using copy-paste, and then loaded that as a texture into the program. Of course, these are not our real kitchen cabinets, but you can see how the colors work together.
I use this to fiddle around with wall colors.

I find the tile itself beautiful. However, I think it is unsuitable for a residential house. I fear it will quickly look cluttered if 100 everyday items are scattered around the room. I think it is a tile for a museum bathroom, a cafe, or an accent wall (here, someone has just tiled their wall along the stairs). The pattern is busy and "design-oriented." That requires a calm and skillful interior design to match. I would not combine it with silver oak. White or light wood with copper handles, or something like that, or an elegant green (patina-style), that would work better. For me, it is more of a tile for a large, public space. Not for a normal residential house.

Pretty! But it is actually quite dark already.

I first had to form an image of the wood color – it’s not dark at all. On a grayscale it’s more like medium grey.

That would be too grey for me...

With a kitchen consultant who is too lazy to click a few times in his software to render you a more realistic picture of your future living situation, I would say: off to the next kitchen consultant.

Often the software, low resolution or a bad graphics card. Or the position of the wall casts "shadows."

I recommend sample pieces of the surfaces. You surely have the tiles at home already?

Everyone’s taste is different. If you like it that way, then go for it. For me personally, the tile is too black, even if there is some silver in it. But I'm also not a black-and-white person; I prefer it more broken or anthracite. For me personally, it would also be too many surfaces: wood (kitchen), then a single-color countertop, silver stripes, tile with silver... I would probably (off the cuff) swap the calm grey of the countertop with the floor look.
