Mix for pointing Toulouse stone

[Catusse-Haut]

We live in Quercy and have done much repointing of white stone.  However, we are helping out some friends who live close to Toulouse.  The area for repointing is the flat reddy brown 'tomette'? stone and grey large galets stones from the Garonne.  I think our usual mix to blend with white stone will be too stark.

Does anyone live in the Toulouse area and have any suggestions of what mix I do and what to ask for at the sablier?
