Geertjan Wielenga: Sublime Text Look and Feel for NetBeans IDE
The highest ranked NetBeans theme on the truly brilliant NetBeans Themes site replicates Sublime Text and looks really great. Click to enlarge the screenshot below to see it in context in NetBeans IDE 7.3.1... I have no idea who is behind that NetBeans Themes site, but it's an amazing contribution to the NetBeans community. Just take a look at the themes on the site, choose one, download its ZIP file, go to Tools | Options in the IDE, click Import and then browse to the ZIP you downloaded...
