Hi there.
Lots of these kits have a list of ~6 paints used with the kit.
Did you buy it from the
GW shop, or somewhere else?
If not, drop by your local
GW store and ask them.
Failing that, someone'll be along son enough to comment.
In the meantime, try potting another post in the Painting and Modelling forum on here:

It's more general than this forum, but painters hang out there who don't just do
LOTR minis.
