Dark theme for Nimbus Look and Feel. It goes well with "Norway Today" editor color scheme. It does not affect other look and feel implementations so you must force Nimbus l&f, e.g. by using --laf Nimbus command line switch. To revert back to the default Nimbus theme you must uninstall this module, it is not enough to deactivate the module!

Sources are available in contrib/nimbus.theme module.

Please report any bugs under contrib/Nimbus Theme product/category.

Dark Nimbus and Dark Metal Look and Feel in NetBeans

Dark Nimbus and Dark Metal Look and Feel in NetBeans
Posted by gliesian on Aug 18, 2016

breaks after 8.0.1

bubergeson, which version of netbeans are you running?

I noticed that in 8.0.2 the editor has a new themeing menu for some themes that come built-in, and they overrule the dark metal theme. Because of this I have kept my version of netbeans at 8.0.1 because I really love this theme.

I submitted a bug report here:

Posted by jeromeb on Mar 04, 2016

Almost there

This is a nice theme but there are some bugs.

First, if you just install the theme but have some other theme selected like Nimbus, then when you are editing a Dialog, JFrame, or any other GUI component and select preview in Dark Nimbus the Editor window changes the Dark Theme which it should not.

Secondly, if I have this theme installed, because I like to use it for development and I want my RCP application built upon NetBeans to also have this theme available, but I want my RCP app to launch with just Nimbus as the default, I had to add the following code in my installer:

prefs.put("laf", "javax.swing.plaf.nimbus.NimbusLookAndFeel");
try {
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {

The first line of code above was necessary since I am launching the app with a different theme then what NetBeans is running. If I just use the UIManager to set the look and feel but modify it to use the Dark Nimbus theme and then launch the app it acts as though it is not fully using it. Some of the icons will be white around them. Also, If I look in the Tools->Options->Appearance->Look And Feel I see that Dark Nimbus is not selected. If I select it and then relaunch the app then it works correctly. If I add the first line of code above then this issue seems to be fixed most of the time.

Thirdly, sometimes I will get errors when my app launches saying that it can't find my splash screen image. This doesn't occur when the Dark Nimbus theme is not being used with my app.

Fourth, it seems flakey. Sometimes my app will launch using Dark Metal. I can shut it down and relaunch it and it will then work correctly.

Fifth, the JTextPane component doesn't seem to set the background color correctly. I had to add the following for it to work correctly:
UIDefaults defaults = new UIDefaults();
defaults.put("TextPane[Enabled].backgroundPainter", c); // c is the color
putClientProperty("Nimbus.Overrides", defaults);
putClientProperty("Nimbus.Overrides.InheritDefaults", true);

Overall, I think this is a great theme but until it is less buggy/flakey I cannot deploy it with my applications. I wish it were added officially to the NetBeans distribution the same way that Nimbus has been added.

How to send patches?

How do I send patches?

I want to change the color of arrows in the JTree component. They are black, and invisible (almost) as such.

Kind regards

Mac-friendly version?

Like some of the others here, I'd like to a see a version of this that works correctly on Mac OS X. The main problem is that the native Mac menu bar disappears!
Posted by bobthedino on Mar 01, 2015

Absolute favorite theme!

Thanks so much for this theme. It is the best ever....
Posted by mattspawn1975 on Sep 11, 2014

works on netbeans 8.0 !

favorit theme.
Posted by HausO on May 10, 2014


I like how it utilizes the versatility of the Nimbus LAF. I'll use this when programming at night!
Posted by Supuhstar on Mar 08, 2014

Mac friendly version

I am also interested in a Mac friendly version like redgibson.

Also, I'm noticing that the output window on the Mac is not converted to dark.

Change look and feel (reverting back to default look)

In NetBeans 7.4 you can change the look and feel under
Options >> Miscellaneous >> Windows >> Look and Feel >> Preferred look and feel.
Posted by estabij on Nov 26, 2013

NetBeans 7.4

has a its own plugin providing dark themes, it's available from NetBeans update center.
Posted by saubrecht on Oct 21, 2013

Not work in Netbeans 7.4!

And it so strange that Netbeans have only one possibility to change the color of GUI.

Ubuntu Desktop advice

To make this work properly
Edit the Unity Desktop file located in:

change the Exec line to read
Exec=/bin/sh "/home/user/netbeans-7.3.1/bin/netbeans" --laf Nimbus

remember to adjust the path point to your instalation of netbeans. IT should be set properly already so just add the --laf Nimbus outside of the quotes.

Latest nightly build still showing search results as black on black (or dark blue)

I'm using the latest nightly build (201306272300), and the search results window is still displaying black text on dark blue background. When you click on something, it does highlight the background as a lighter color, but if you have a huge list of results, it's not exactly efficient to have to click on each one to find what you're looking for.

7.3.1 - no theme selection drop-down

had the same issue as Deldadam... no theme drop-down under
Tools > Options > Miscellaneous > Windows (tab)

I installed a nightly build : 2013-06-19_17-09-51 (can be found here: http://bits.netbeans.org/dev/nightly/)

the theme looks great and works well!

Posted by vasheck on Jun 21, 2013


In nightly build 201306191709 seems perfect. Many thanks to devs.

How to install/Unintall

I tried to install it, nothing worked, but now I can't seem to uninstall it.
It tells me its installed, but I cannot seem to remove it.

How to switch to the built-in theme

I'm trying to figure out how to switch on the theme in NB 7.3.1. Everybody is referring to "Tools - Options - Windows" to find the option, but I don't have such. I've got only "Tools -> Options -> Misc. (panel) -> Windows (sub-panel)", but there is nothing that would allow me to use this theme.

I'm on Win. 7 64-bit.

AFAIK this theme is included in NB 7.3.1, and I don't need to use the plugin from here. Am I supposed to know this differently?

bug 7.3

When u are opening a new file
the new file window letters turns black
if u move ur scroll on the rigth window

Posted by rocknathan20 on Jun 06, 2013

Working well on Suse 12.3

Added the plugin in Netbeans, it wants to restart, after restart doesn't work yet, but as described in the introduction, I edited
netbeans_default_options=" --laf Nimbus"
Then it works.

Posted by atimmerma on May 10, 2013

Re: Not Working

navets, massiws: you need to switch to Nimbus look and feel. Try running the IDE with --laf Nimbus command line switch.
Posted by saubrecht on Apr 15, 2013

Not Working on fedora

Nothing changes in the background. But the text turned white in white background making it unreadable..
Have to uninstall and delete all netbeans folder to fix this.
Posted by navets on Apr 15, 2013

Not working on Linux Mint/openSuse

Installed on Linux Mint/Cinnamon/Mate and Linux OpenSuse/Gnome/KDE: I can't see any difference.
File and directory names in Project and Navigator windows (on the left) are visible only if selected (font and background colors are white).
Is there a workaround to make it works?
Disable (without uninstall) the plugin the style return to standard settings.
Posted by massiws on Apr 09, 2013


>>> would be cool to create a theme like the monokay (sublime)

Posted by milkovsky on Apr 06, 2013

Re: Problems

Everybody, try the latest dev builds, it has much better support for dark color themes.
Posted by saubrecht on Mar 29, 2013

Same problem on the auto completion popup

I'm using nighty version and I've the same problem as centai. The auto completion popup with methods & objects (at least with PHP) is dark blue on black.
Posted by kevin39 on Mar 29, 2013

Nice theme but problems with dropdown

I am using this theme for NetBeans 7.3. It looks good, but the dropdown of NetBeans which lists members and methods of an object is just not readable (black font, dark blue background).

I did not find any way to change this.
Is it possible to fix this next version?
Posted by centai on Mar 28, 2013

Not working on Fedora

As someone already pointed out, this is not properly working on Fedora. In my case, I installed the plugin and saw no difference at all, regardless Look and Feel settings.
Am I missing something?

re: Revert back to the default Nimbus theme

Deldadam: there will be problems when you switch to other look and feel than Nimbus
Posted by saubrecht on Mar 12, 2013

Revert back to the default Nimbus theme

You say in the introduction: "To revert back to the default Nimbus theme you must uninstall this module, it is not enough to deactivate the module!"

Well, I'm only deactivating the module, and it reverts back to the default Nimbus theme succesfully - at least on my Win 7 Prof. machine.

Dark Nimbus

redgibson: Good point, please file an RFE for it in NetBeans bugzilla, thanks.

Rafaelll: Try latest dev build instead of this plugin.
Posted by saubrecht on Feb 27, 2013

Does Not Work on Linux Mint

I installed the plugin in my NetBeans 7.3 but it did not work as expected (only the editor tab got a little darker).
Does this work on Linux Mint 13 (my OS) ?
Posted by Rafaelll on Feb 27, 2013

Mac friendly version?

Hi I am using netbeans 7.3 on OS X 10.8.2, this pretty much hijacks all the normal menu operations into the application window in an X11 style.... perhaps theres a way to have this keep the menus in a natively managed format? Other than that I very much like the dark theme.
Posted by redgibson on Feb 27, 2013

Latest dev builds

kevin39: Please report it as a bug, thanks.
Posted by saubrecht on Feb 27, 2013

I'm using 7.3 build 201302252300

@saubrecht thank your for your fast reply. I'm using 7.3 build 201302252300 and same problem...
Posted by kevin39 on Feb 27, 2013

Latest dev builds

kevin39: You need latest trunk build and switch the look and feel in menu Tools - Options - Windows, NetBeans versions 7.2 and 7.3 have some bugs when using dark color theme.
Posted by saubrecht on Feb 27, 2013

Perfect but 1 (big) problem for me...

Your plugin is excellent but my search results are dark blue on black... So it's unreadable !

How to improve it ?

PS : I'm using the last build but same problem on last stable 7.2
Posted by kevin39 on Feb 27, 2013

Latest dev builds

Everybody, try the latest nightly builds. There are many bugs fixes and even a combo box to switch the current look and feel and/or theme in Tools - Options - Miscellaneous - Windows
Posted by saubrecht on Feb 21, 2013

Not working on fedora 17

I've installed this plugin on newly released 7.3.
Saidly enough it had same problems as leagurb described.
Posted by DoniRS on Feb 21, 2013

Nice colors with side effects

I liked the colors, but then decided to go back to the standard ones. The plug-in left some drop-down menus wacky.
Posted by leagurb on Feb 20, 2013

...and 'dark black' colors are even less visible on dark background

Open Tools -> Options -> Keymap. Try to read the content of 'Shortcut' column :)

Anyway it is really nice theme, although a little bit 'space consuming' 'cos the Nimbus LaF.


Posted by Deldadam on Feb 13, 2013

Dark blue colors are less visible on dark background

The theme is nice, but I suggest to replace the dark Blue colors on dark background (javadoc tags, html tags in javadoc comments, file names highlighted due to versioning status) with some kind of a light blue color, such as Cyan.

Nice theme.
Thank you for that <3

Posted by leodouglas on Jan 16, 2013

Dark icons needed

Thanks, this is very cool !!!

I think to be really useful most of the icons would need to change to better fit into the dark theme.

Source files

are available in contrib repository in 'nimbus.theme' module. Patches and tweaks are welcome.
