We are having a new patio. It's a massive area and involves a lot of levelling so need a digger etc etc. However, I'm not 100% sure about the colour of the slabs. They will be Indian sandstone and I was thinking of grey with charcoal brick edging. I've got the idea (from who knows where)that grey is the most natural colour rather than a sandy/ buff colour and that also grey doesnt discolour so much. However, even the man who's fitting it says he wouldnt choose grey!!! Thanks for any advice
