I recently saw the colorized dragon hoard that was listed here I downloaded it and while it was a great attempt the colors used were not what I had envisioned it looking like. My wife is a professional digital imagerist so I handed it to her and asked if she could work on it. She never fails to amaze me!
Well by the screenshots below I am sure you can see what I mean.
Please click the link below then on mods to download it

To install simple extract right to the Horizons folder, for those that would like to manually install it the correct path is:
C:\Program Files\Tulga Games\Horizons\resources\interface\themes\default\ textures
and just copy paste them in this folder.
