Had a lady call me up in a right panic. She had just had a new kitchen fitted in a property she had just moved into, and when they removed old kitchen & fitted new kitchen she was left with a floor like this.
I managed to find some of the same tiles and left her with a floor like this. And a very happy customer. This is why you should tile a floor then fit the units.
That is the colour of the grout. The old grout needs cleaning.
