As far as I'm aware, there isn't one with purple foliage - there are some with bronze new foliage, such as C. montana 'Ellizabeth' or 'Freda' 'Odorata' or 'Tetrarose'.

Ive got one in the garden at the moment and the leaves r (well perhaps purple was the wrong description) maroon, deep reddy colour (hard to explain really).
Wish id kept the label now

I have 'elizabeth' and it has bronze/purplish young leaves but the open fully to a dark dull green
