I think it will be difficult to find something to match. I could be wrong but, from the photo, it looks like the drive was some kind of crazy paving made up from broken slabs - 2 or 3 different colours (?) which have since weathered & faded. So if you found something similar to replace them, the colour would most likely be brighter. What happened to the parts of the drive that the builder took up?

We're doing a total ground floor renovation on a late Victorian townhouse in London and I'm attracted to the idea of using tile in the entry hallway - maybe something light and/or colourful to lighten up the space, which will be dark. I also want to tile the walkway up to the house at some point in the future (when we have recovered financially from the renovation!) Thinking ahead, should the tiles match? I like traditional Victorian encaustic tiles for the outside (e.g the Lambeth pattern in beiges and blues), but I was thinking of something more modern/maybe in gray and white for the hallway. Should they match?

Thanks for suggestion. This pinkish does match the colour in the tiles... And the little ones toilet seat :-) Taking a look via Google Lens.... See what comes up
