According to the Silverprint.co.uk online catalogue, you have a choice of
Agfa, Fuji, Ilford, Kodak & Tetenal RA4 papers (in the UK at least).

Personally, I'm colour blind so I never use the stuff. I spent much of my youth wondering why so many women liked that awful looking pale blue lipstick: turns out, it is actually pink... ho hum....
