Is there any dye that I can mix in a two part resin wood filler.
I have some natural colour Ronseal resin filler left over from a job that I
want to stain dark brown and use for something else. Any Ideas.

Umm well a Ronseal two part filler is unlikely to be epoxy. It will most
likely be a polyester resin. Loads of colours available, simply look for
gelcoat colours. Most chandlers sell kits of a pack of tubes of colours
for matching repairs.
