Paint schemes for mounted Realm of Chaos warriors

I'm currently painting up a mounted unit of Citadel Miniatures Khornate Chaos warriors for Oldhammer Weekend and I turned to the old Realm of Chaos cavalry in Bryan Ansell's collection for some inspiration on painting the horses. If you're also looking for a little inspiration then take a look at the images below - many of these can be seen in the pages of the two Realms of Chaos books and in the pages of White Dwarf issue 104 (and probably several others from around that time).
