Epoxy Resin Dyes

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.

Epoxy or polyester resins are both happy if you colour them with a small quantity of artist's acrylics, as purchased cheaply from any craft shop.

Plenty of other suitable dyes too.

OK I assumed that it was epoxy because it was 2 part. It doesn't actually say what it is, just 2 part resin based.

Cement powder dyes would probably be ok and are easy to find. They're just raw oxide pigments so there won't be any chemical compatability problems. With water soluble dyes there almost certainly will be.

Actually MOST powder paints work pretty well.IIR carbon black inhibits setting tho.

Some specialist sites sell special pigments..used in gel coats for galss fiber work.

Not a vast range of colours though. Purple isn't cheap!

Cement stains are pigments, rather than dyes, so there can be problems in getting a good mix if you put them directly into epoxy. Easiest way is to wet them with a spot of acetone first, then mix that wet into the epoxy.

Yea I have seen those but they are in large tins but the acylic paint or pwder paint looks a good bet.

Stick to dry colours. Once a pigment is dispersed in a particular medium, like acrylic, it doesn't take kindly to being mixed into another.
