This resources became the default bright, dark and blender theme included in Krita 2.8 and newer versions . You probably don't need to install this.
A small post to share the colors themes I did for the new feature of the next Krita 2.5 : changing the color theme on the fly.
It's an advantage while painting to not get surrounded by a too bright user interface or get influenced by teinted warm or cold grey user interfaces. It's also confortable to have many choice and switch them according to your mood or type of work you need to do. ( ex: bright interface for line art or sketching , mid grey for precise color works , dark for late night working ...etc... ).
