Thanks very much chaps.
Yes Andy, as Wojtek stated, there are various dyes or pigments which can be added, either for translucent colouring, or a 'solid', opaque finish. A quick look on-line will bring up a few outlets, some of which have some useful 'How to' videos.
The stuff I used was a two-part polyurethane resin, with one part already coloured that cream colour, and it's a 'fast cast resin', the type most commercial resin accessories are made from.
I've seen the same stuff, in the videos, on American / Canadian web-sites, so it should be easy to find if you decide to get some, and it's not too expensive either - my 'kit' cost around £9 or £10, from memory, which included a tub of RTV silicone mould material, and the bottle of catalyst, plus the two 125 g bottles of the resin, which is enough to make hundreds of small parts.
In addition, I've just got, last week, a spray bottle of mould release agent, costing around £6, more to protect the 'masters' than anything else, although with the small size, and regular shape of those, I probably didn't need the release agent. The spray should last ages, as, although three coats are recommended, presumably for larger, more complex shapes, I only gave the 'masters' one quick spray, which was a quick burst, as the parts are so small, and it was immediately evident that was enough !
