If you use ClipIt in Ubuntu 11.04 it uses a non-monochrome icon. So made some work and ported 2 different icons to get a monochrome icon for ClipIt, my favourite Clipboard Manager.
The icons are made by RamzeaG and by Tiheum (from Faenza). Thank you guys, for your great work.
1. Decide which icon you prefer, both are nice
2. Run nautilus in sudo. ALT+F2: gksu nautilus
3. Copy one of it into: /usr/share/icons/Humanity/actions/22
4. Restart ClipIt
5. Enjoy :)
These icons should also work for other clipboard managers. ;)
