There is a blue moleanos limestone as well which is more silver grey and may be a better match although from memory it still has patches of beige in it. Might be worth getting a sample. I don't have experience of real marble floors but they sound like a nightmare to keep clean in a kitchen. Have you seen porcelain tiles made to look like marble-they are actually really nice. Have a look at casa dolce casa stones & more range for examples. I have their smooth lipica tile-not marble but it matches with purbeck stone and moles breath in terms of colour.

Many thanks to everyone! After seeing them again and laying in a right way I decided to keep then. And of course go for Cooacabana with more black in it with wavy pattern (rather than linear). These tiles cost me £17 per sqm and are a bargain for the quality that they are (getting them from abroad). Apart from the pattern they are very white which overall would keep the floor colour white.

there is not a big difference between the worktop ( it is more shiny) and tiles for walls you have chosen. About the concrete effect, the finishing is matt , so it is not that much shiny but the advantage is not slippery, I think you have done good choice unless you choose your walls tiles matt also ( to me better choice) make sure your silicone is colorless otherwise it will stand out really bad when it is finished.

Hi Bahar- my mother has marble countertops, which she installed with her full kitchen renovation circa 2010. For many years afterward she constantly fretted over keeping them in pristine condition, to the point the rest of the family felt pretty uncomfortable being anywhere near the countertops. She’s nearly 80 now, and has relaxed a bit thank goodness. The countertops still look lovely- the sealers and her diligence have done a good job- but there have been some chips, and mending attempts haven’t worked particularly well. She’s still happy she chose them, but I’m not certain she would do it again.
