I have the same issue with oxygen. Every time I start eclipse some values are reverted to the wrong values. The ones I noticed are javadoc color and background (black), colored labels - match highlight (also black) and c/c++ editor text font (consolas regular 10).

All the affected items have a default of some sort (they are either "set to default" or "override default"). Seems like the plugin can't handle such items correctly.

To add strangeness to this behaviour: you can't simply "revert" the value - it does not save the reverted value. You first need to pick a new value, apply and save it, and only then the "revert" will restore the values intended by the theme.

Are you using our light theme (now part of the 2017 CI 9 release) or dark theme? If you switch to the other, just to test, do you still experience these problems?

Unfortunately there are still some situations where the preferences just do not behave. The good news is that we believe we know why, and the next release will inclue a fix. Let us know if you would be interested in testing a pre-release with the fix, we'll let you know when it becomes available.

Just tried with light gray. Same result: black for colors, consolas regular 10 for font.

When I set the comment color,it is different from the actual display, such as set to (0,128,0), and is shown as (191,255,191).

We're sorry that you are seeing this issue but thanks for reporting it. I see the same issue and I've raised a bug report for development to investigate.

I wasn't thrilled to open Eclipse to a popup asking me to try something out.

I clicked "agree" to checkout DevStyle and see what it is.

It adds some weird branded startup menu. Which does what?

Each time I open Eclipse, I have to select my workspace. It then takes several extra seconds to open the editor. Can you believe this? Eclipse already takes a while to open.

Granted, the ability to choose icon packs is nice, as is the theme itself as always. But I'm not interested in a foreign startup menu crapping up my development experience.

Dev, your theme is appreciated. Can we keep it to that?

bfernandestdp's picture


First, I'm glad you like the theme, thank you - if you haven't already tried them, DevStyle adds attractive light themes as well.

You can turn off the startup experience by clicking the "Use Classic Eclipse Startup Dialog" link in the bottom left of the Launch tab of the startup dialog, taking you back to the default Eclipse startup behavior, while keeping other parts of DevStyle enabled. We do realize this link is not too easy to find, and our next release will make it more obvious. You can also turn it off from the Darkest Dark preference page within the workbench.

The Enhanced Startup Experience gives you the ability to quickly locate resources you were working with, especially when you've been using multiple workspaces. In a subsequent release, we'll be adding simpler wizards that help you quickly start new projects across an array of technologies, and we'll add more features over time. Of course, we realize this won't be useful for everyone/everytime, so it's only an optional part of DevStyle - you can turn it off, while keeping the other features like light themes, inline find, and the breadcrumb toolbar still enabled. For more on the startup experience see this doc: and more on DevStyle in general, see here:

Hope this helps, thank you again for your comment.

today, the theme pushed a update to my neon, it asked for restart, then my neon cannot start anymore.....

twebbcke's picture

Ouch!  Certainly not the expected nor usual behavior.  Mind sharing some details in our support forums such as error from configuration/13131313.log (different number of course)?  Thanks!

dsfljkgaljk's picture

How can I fix that. I love the theme but without changing that its worse because that bar is so bright.

tweddlelmg's picture

Thanks for the comment, Dsfjkla Sfljkgaljk and for trying Darkest Dark!

This isn't a known problem but perhaps you could check for updates first and, if it still happens, let us know the details (including your OS and version and a screenshot) over at our support forum. We'd love to resolve this for you. Our forum can be reached by clicking on the support link icon above (the circle with "?" in it) then going to the Theme Problems forum.

I love this plugin!!!

My only complain is with cut and paste.  If I paste into something that maintains formatting (for example, Skype for Business which my company uses for instant messenger) I get all of these grays and pale blues against light blue backgrounds ... it is hardly legible. I don't know if there is any way to deal with that?



twebbcke's picture

What file type are you pasting into?  Normally coloring comes from the code syntax, not the actual paste buffer -- normally Eclipse takes the [plain text] format of the copy buffer.

Glad you like it!

sthompsonrj7's picture

I'm pasting into Micrsoft Office 2013.   This is really easy to reproduce ... using the default color scheme, go to an XML document like a POM, copy multiple lines of the POM to the clipboard, then paste it into MS Word.  The result is sky blue text pasted into a white document.

I have an issue in oxygen 64 version after installation.

In short, all sections in preferences are empty.  Actual sections on the left side are present, but right panel is empty for all sections.

bfernandestdp's picture

Andriy, apologies for the delayed response - I can't say we've seen something like this ever reported. What OS are you on? If Linux, what Windowing system and theme? Feel free to create a new topic on our forums: for detailed assistance.

I install the dark theme and Eclipse Oxygen fails to start and crash with:

!ENTRY org.eclipse.osgi 4 0 2017-08-10 10:05:29.794

Odd!  If you could share the full stack over at our forums -- we'd love to have the details of this issue.  This doesn't seem like anything we've come across before.  Cheers!

I think your theme has cured my headache.

A much needed escape from Eclipse's stare-into-the-sun defaults.




eleonard4iq's picture

Trying it out and found a small annoying instance, if you copy & paste a class and are taken to the accept default name, or rename the class option, the suggested classname (whichever class you have copied with a suffix of 2 usually) will now have white text yet be highlighted with a babyblue colour background making it unreadable. If you then move the arrow key back, the baby blue background higlighting goes away but now you cannot see your cursor either. 

This makes it a little fidgety for this operation. functionally it works, but in UX terms it's not the nicest.

lsea's picture

Thank you so much! I have been looking at white UI and recogn eyes theme for so long! Now.. it. is. OVER! <3

I created an ccount just to post this! <3 <3

mcharestw5g's picture

Been using it for few days now and feel the need to mention how great it is.  After all these years seems like the beast of a task that is making a Dark theme under Eclipse has been tammed!

Big thanks.

After installed the latest update, I constantly get a pop up message which is Java heap size, connection timeout on org.genuitec.theming.ui.

Thanks for all the great reviews - for the support requests here, we'd strongly ask that you use our support forums as it makes it so much easier to get details, reply promptly, and more importantly, use the attachment feature.

atfer I installed the theme eclipse no more starts..

OS: ubuntu 16.04

eclipse c\c++ neon


error log:.

[Error log removed by Eclipse Foundation]


twebbcke's picture

Thank you for providing the details here.  I have cross-posted this to the Darkest Dark forums and would ask that in the future, you post logs there -- it is a lot easier to follow up and actually supports attachments instead of huge messages here.  Thanks!

I prefer dark themes and Neon was giving me problems with themes across the on my linux computer. In the rtc client in dark theme, some words were black, So I tried light themes and in the light themes, links were very light blue. But with this Darkest Dark theme, everything seems to be readable.

I like very much the look and feel of this plugin, but my IDE gets too slow after installing it. The Console Window is unusable and switching tabs takes forever.

I tried with a fresh install of STS and with a fresh install of Eclipse Neon + STS. Both of them started to have those problems, making them unusable for developing Spring Boot Apps.

I would like to point out that I use Spring Boot with Developer Tools (spring-boot-devtools) for auto build and live reload.

twebbcke's picture

Given popularity of STS, we do actually test with it and haven't seen any direct performance slowdowns -- right now we are unable to replicate the performance issues you are seeing with Spring Tool Suite and Dark Theme. What would be interesting to know is your workspace setup, specifically the type of projects in the workspace.

  1. You mentioned Spring Boot Apps in your summary. Do you also have several other spring projects in the workspace? Which spring framework(s) are these projects using? Are these Maven projects? Are there many Java classes in these projects?
  2. Which spring specific validators enabled for these projects? Are they defaults or you have additional validators enabled?
  3. When do you see the performance issues? Immediately after launch or when creating projects or other? Do you see any background jobs running at this time?
  4. Which appserver are you deploying your projects to?
  5. Are there are any additional settings that you think might be interesting to share?

Ideally if you could respond with details on our forums (see Support link), that would be superb!  We are striving to make Darkest Dark run smoothly across an array of Eclipse IDEs and your assistant will help greatly!

Works really nice, My primary motive was to reduce the strain on my eyes while working.. it has reduced drastically..
One thing I noticed was , Progress bars are not aligned properly, as in the progress "blue" bar is below the blank space of progress instead of running over it.
also while launching eclipse, The workspace prompt is kind of messed up in colors with someportions like checkboxes being black while the rest of the window is "off white" as was before the installation of the plugin..

Hi Arun,

Thanks for the feedback. Would you mind posting issues with screenshots in the forums?

This is a must have if you enjoy dark themes in any IDE. Brings Eclipse into the 21st century. Thanks for delivering this!

awatsoneas's picture

Thank you, Scott. We loved your comment so much that we made it into a quote card for our social media. Enjoy Darkest Dark!

I couldn't find any support forums so I'm posting this here.

I have to fight with the theme overwriting my custom syntax coloring options every time I open a workspace. I've had to resort to customizing syntax and then exporting the preferences for each workspace I have. Then, when I load a workspace, I have to import the preferences to put back all my custom syntax coloring.

Would be nice to get this fixed. Love everything about this otherwise.

awatsoneas's picture

Hi Aj,

Our tech support is already working on your issue. Please post it on our forums so they can reply as soon as they have an answer. We are glad you are loving it!!


awatsoneas's picture

Hi Aj,

Here is the link to the forums genuitec . com /forums (Eclipse won't let me post the link) would love if you can post there the issues you are having and any additional comments/concerns etc. We are glad you are loving it, though! :)

Now I remember, I didn't want to have to register :(

Thank you, not sure how I didn't find that.

This theme started to be in the top 10 downloaded Eclipse plugins in no time. This points out how users consider important a good designed theme for Eclipse.
Some things I would like to see (take them as feature requests):

1) Syntax highlighter: quite unstable now, sometimes it visualizes strange characters or odd color schemes that seem to be completely random (speaking about Java here, I haven't tried much for other languages).

2) More color schemes for code syntax: those from eclipse color theme are great. And that project seem to be dead. Quite a good opportunity here ;-)

3) I love the icon style: I don't know how legal would be to rebrand some icons, but I would like to see some better icons using this style for the project explorer and maven imported projects, various mime-types, new project creation and, if possible, the most popular plugins for Eclipse: JBoss Tools, Spring STS, eGit, MercurialEclipse, etc. Expecially the Docker Tools, they refuse to use a whale for the perspective icon.

4) Stability, stability, stability. A theme has a tremendous important role: if syntax highliting goes crazy, it prevents people from working comfortably.

Thank you.

twebbcke's picture

Awesome Feedback!

1) Syntax highlighter: quite unstable now, sometimes it visualizes strange characters or odd color schemes that seem to be completely random

Mind providing some screenshots or GIFs on what you are seeing? You can tweet them to me at @timrwebb or drop them on our forums. We really aim to strive to make this rock solid. Regarding syntax coloring, that's an odd one as the theme doesn't actually do anything fancy for syntax highlighting other than just provide colors -- curious that it impacts reliability but we'll look at what you share and see what we can sort out!

2) More color schemes for code syntax: those from eclipse color theme are great. And that project seem to be dead. Quite a good opportunity here ;-)

Excellent -- this one is already on the way. We allow you to switch between Editor Color themes in 2017 CI 4 coming out in 1.5 weeks and even import your favorite existing Eclipse Color Theme right into Darkest Dark. No need to install ECT to benefit from efficient color selection, and with the benefit of not smashing thousands of preferences into your workspace.

3) I love the icon style: I don't know how legal would be to rebrand some icons, but I would like to see some better icons using this ......

We continue to strive to brand more icons and would love to have more contributions from users like you! Have you tried to install the Icon Designer to contribute some of your own suggestions? Let us know how it goes over on our Darkest Dark forums if you don't mind!

4) Stability, stability, stability

Right there with you!

The Package Explorer is finally useful again! HDPI screen and this is a must.

Combine this with the preference settings that emulate the Intellij Darcula editor settings, and the combination is bliss.

Should I repeat this theme is great?

awatsoneas's picture

We would love that. Can't get tired of reading that. :)

Finally! This is THE Darkest theme I was craving for Eclipse!! At last, I have a quite smooth foreground and background coloring - along with so cool icons - to create, run and debug my Java applications =D My #CoderLife is not every in breath I take but in the great experiences that take my breath away - just as this awesome darkest theme is doing at this very moment!! You should really try it out! Most likely you will also enjoy this amazing pleasure to the eye and bring a beautiful zen-workspace to your projects ^_^
