I bought some resin bonded gravel for use between slabs on a pathway from this company: http://www.resinbonded.co.uk/
It would be quite expensive for larger areas and is fairly labour intensive to lay.
Have you thought of using pattern imprinted concrete? There are a number of companies that do it, it's less expensive than resin bonded gravel and you can get a number of different colours and paterns to make it look much nicer than standard concrete.
