'Stone'-coloured cement/render pigment/dye?

[JohnW2]

Can anyone recommend a dye/pigment which results in concrete/mortar/render ending up roughly 'stone-coloured' (a bit like one common sees as the base of pebbledash, and often just with render)?.
Of the various sources/makes I've tried, variations on the theme of 'buff' sound like the most promising but, more-or-less regardless of what one uses them to colour (anything from sand-coloured mortar to white ready-mixed render) I end up with something far more 'yellow' than I really want.
TIA for any advice!
Kind Regards, John

I've just noticed that I never got any replies to this back in November - has anyone got any thoughts/suggestions/advice?
