Finally... (sorry for the wait) The Aloha Color Theme for NB 6.1 is available for download.
The original version for 6.0 (here) had issues coming over. If you have not updated yet, you will want to with this list of features.
Aloha Color Theme for NetBeans
After the download, open NetBeans and go to Tools > Plugins. In the Download tab, add the AlohaTheme.nbm and install. To use it, just select it from the Fonts & Colors profile "Aloha."
You will want to go change the "Diff" colors which are not included in the theme (not yet anyway). Color of Added Text: Black, Color of Changed Text: Dark Grey.
