I came up with a good alt scheme for my Rohirrim, even made an article for them in the days of the old TLA
Basically I used a more vivid green on their cloaks (dark angels highlighted through goblin) and on the other cloth and shields I used a deepish blue. For the armour I painted the mail, bracers and edging to the helm and very clean silver and the leather parts of the armour I left black and painted with gloss varnish.
The overall effect was strikingly different, mainly because unless youre painting haradrim or high elves almost no-one uses blue for lotr minis I'll check later and see if I have any pictures on my laptop.
