I have to do some repointing on an old stone farmhouse in Normandy.

I've put a couple of pictures at http://www.dthorpe.net/lafolie/

The cement used here is white cement with some gritty sand and some
ordinary sand. What kind of proportion cement/sand/grit sand/ should
I use for the correct hardness of the mortar and to get the sandy
yellow colour shown?

I've looked at all the info I can get about proportion/ hardness of
mortar but it's mainly confused me so far!

Anyone who could look at the pictures and unconfuse me a bit would be
most welcome.
