Here is my (I'm posting on ableton forum as klinikal) skin set of black skins for Ableton Live which I made some time ago. Enjoy!

How to install skins
-------------------------------------------------------------------------
On Windows systems
Extract and copy skins to C:....Program Files..Ableton..Live X.X.X..Resources..Skins
X.X.X = version number of Ableton Live.
------------------------------------------------------------------------
On Mac OS X
Skins folder is inside the Live application.
Right-click (or ctrl-click) the Live application and select 'Show Package Contents' to access the Skins.
