I am using the zonColor DarkNight theme on Ubuntu 13.10 and am quite pleased with it. I would like to have a similar theme for Ubuntu 14.04 but so far I could not find a single dark theme available. Is it possible to port a theme from Ubuntu 13.10 to 14.04? Or must I wait for zonColor (or whomever) to release new themes for Ubuntu 14.04?
NoobsLab has made available through their PPA a new theme entitled Ambience-Dark-Red. It retains the default Unity decorations and icons and simply tweaks colours. Although not as good, it is at this stage the closest to DarkNight you can get for Ubuntu 14.04.
To install Ambience-Dark-Red:

It can be install with the following terminal commands:
An alternative, also from NoobsLab is the GnomishDark theme:

To install the Meditarranean package:
Numix Bluish is a variation of the Numix theme, with what to my eyes seem violet and green hues. There is again a good deal of customisation regarding icons and window decorations.
