This theme supports Ubuntu 16.04, Mint 18 and Distros with GTK 3.18 and bellow only!

We have a New theme called Vivacious Colors GTK!!!
It will most likely receive GTK 3.20 support first. but has not yet.
It looks alot like this theme but with many improvements
And supports GnomeShell and CSD alot better. GTK 3.18 Only for now.

This Theme is meant to go nicely with our
Vibrancy Colors Or Vivacious Colors Icon Themes.

 Or any other GTK Icon theme you see fit.

Ambiance & Radiance Flat is a Modern, Beautiful and Vivid Re-imagination of the Ambiance & Radiance Color GTK 2/3 Themes. It features a Modern, Clean And "Flat" look in your choice of 13 vibrant colors. Despite the name "Ambiance" the theme has been re-designed from top to bottom. And is a theme of it's own. A theme For Ubuntu, Mint Or any Distro and nearly any GTK Desktop.

Ambiance and Radiance Flat Colors is a NEW theme based on Ambiance. Re-imagined and Re-designed by RAVEfinity. It borrows some inspiration and similarity to stock ambiance. However we have taken it to another level with seamless tool-bars, menus and beautiful crisp clean simple look everywhere. With some awesome punchy colors. We urge you to give it a try.

With fully integrated and tested support for: many of the popular desktops Including: Unity , Cinnamon, MATE, XFCE , LXDE , OpenBox , Gnome Classic & Fallback. And Now Gnome Shell in 15.04 version (GTK 3.14+ & 3.16+) 15.04+ Builds Now Supports Gnome Shell. We have reworked everything, so now one theme works on all desktops no separate versions cluttering things up.

Ambiance & Radiance Flat is not by or endorsed by the original Ambiance team. It is a NEW Fully flat ambiance like theme that is Designed by the RAVEfinity Open Source Design Project, It has been in planning & development for a long awhile. Completely redesigned top to bottom by RAVEfinity with main code based on Ambiance & Radiance Colors (Another theme By RAVEfinity) & Stock Ambiance. We keep some design elements of stock Ambiance but we have also redesigned lots of parts on our own. A lot of new design work has gone into this. See bellow for full credits.

15.04.5 - Fixes Grey bands when scrolling on some GTK 3.16 Apps (Gnome Rubber-band Issue), Fixes White Gap on top of Nautilus sidebar in GTK 3.16 and Makes theme ready for Firefox when they switch to GTK 3 later this year.

All other desktops have and continue to work fine.

15.04.3 - Should be fully GTK 3.16 Ready, Makes Crumbbar/Open Directory State in GTK3 toolbars look correct (Like 14.04 build)
Fixes Default button highlight in GTK Headerbar apps. 

15.04.2 - Fixed Background Wallpaper With Desktop Icons on GnomeShell Issue.

15.04.1 - First release of 3.14/3.16 Branch. Completely ported theme on top of new Ambiance supporting these builds! Not backwards compatible but 14.04 LTS branch is identical.

14.04.2 - (LTS Branch, Still Supported)- September 2015 we had go back and make a small unexpected tweak for Cinnamon and Mint 17.2 As they changed how desktop selected colors work in 17.2. But we went back and fixed it because when we say LTS is supported we mean it is supported!

14.04.1 - (LTS Branch, Still Supported)- This was the First Released version of the theme (We did alot of testing and work and got it right) but this theme is based on our well maintained and highly developed code from Ambiance & Radiance Colors. That version has been through over 14 releases (With 8 just for 14.04 LTS)


  1. Seriously, absolutely love your work! I haven't seen may other themes designed with Ubuntu in mind that are at this level. Some other themes look nice at first glance, but start to fall apart with certain UI elements and combinations thereof. Paired with the Vibrantly Simple Icon Theme, this just looks stunning. Cheers!

    1. Thanks for your comment. It means a lot.

      We spend a lot time developing and refining things. And on top of that testing and making sure things look right eg. No off colors or unreadable text. This is why we tend to have "Big" Releases rather then small little ones all the time. Because doing this is sorta of like a software or game "production" for us. And thats how we run it. It's funner that way.

  2. These are awesome!
    thanks so much for your hard work!

  3. Hello, I think this is an issue. I've installed all the dependencies (engines) needed but the ambiance theme looks clear on my system (many if not all windows look bright not dark), is this a problem or is this the expected behaviour?

    1. Sorry about the issue you are having, This should not be happening. What Distro, Desktop and version of that distro are you using?

  4. Thank you for making and maintaining these amazing themes!
    There is one minor issue with flat ambiance and radiance themes. On Alt+Tab switching, window previews get a highlight which is still orange in all color variants. Numix theme somehow fixed this issue and the highlight matches the theme.

    1. Thank you for your comment! it means alot.

      And thanks I will take a look at that and try to find a fix. What desktop is this happening on Unity? or another?

  5. Do you have a change log somewhere, to see what's been edited during a certain update?

    1. We did not write one for the initial release as so many things had to be done.
      But any update releases we try to give details in the "Release Notes & Manual" link at the top of the page.

      Or Here

      Thanks for the question, I think I will consider putting that Info at the bottom of the page instead.

  6. Can this work if I'm using lnux mint 17.1 with a xfce desktop? how should i install it? I tried adding the ppa but it says 'No JSON object could be decoded'.

    1. Hello. Yes it is fully fully XFCE ready. It should work with the PPA not sure why it's saying that. however you can grab and install the Debs as well (Further down) then simply active the theme in Xfce Settings appearance and Xfce Settings Window Mangaer (For the window borders.) Just make sure to download 14.04.1 if you are on linux mint 17.

      Hope this helps.

  7. Great theme. I love how manycustom combination available there

    1. Thank you for the kind words. I am very glad someone noticed that part :D It takes along time to have all of those haha.

  8. Very like your theme, thank you for a great work.

    But I faced an issue on a GNOME 3.16.2 in a Fedora 22. The bars that appears in default gnome theme, when you scrolling text field or a list to a maximum does not appears with this theme. Instead of them there are gray empty fields, that cover a little part of list or text, so its cannot be read there.

    Screenshot of this issue: (in gedit) (in nautilus)
    Same issue appears in all programs that have same fields.

    Its really braking the perfect look of this theme :(
    Sorry for bad english.

    1. Thank you for reporting this. It is actually a issue with the new rubber-band scrolling system in 3.16 interacting with the theme. We need to find a way to make them play nice together. There is no published spec so we are on our own trying to find a way to do this. I hope we can find a way to fix this very soon. Sorry about this.

  9. I am using BackBox (ubuntu based OS) with XFCE, what's wrong with the title bar?
    The title bar shows the same color when i try to change any theme. Solution??

    1. Hello. I think the issue you are seeing is because you need to go to XFCE settings and Select the Window Manager Pane/Option then the desired theme from there as well. XFCE does it that way you have to select themes in two different places. Hope this helps! :)

    2. Yeah, i figured it out my self :D
      thanks for the help anyways.
      After too many searches this theme was the first theme for me to switch from the stock theme.
      Thanks for such an awesome theme.

  10. The themes crashes xfce4-terminal when I select "Appearance" from preference.

    1. Sorry for your issue. That is very strange as I have never seen this. Can you close the terminal? and just open it from the menu , select a theme and then use then use everything regularly?

      I have never seen this happen but I will test. The only thing I can think of is the Appearance Window trys to create previews for all the themes in xfce so it takes a sec perhaps this makes the xfce terminal instance mad?

      What distro is this? Thanks.

    2. Sorry, there was a problem with xfce4.
      I thought it was the theme causing the issue, because as soon as I change the
      theme, the problem did not happen.

      It seems that the fonts were causing the issue.
      After installing ttf-dejavu and ttf-droid from the repo, it was fixed.

      I will continue to use your theme which I think the prettiest and like the best!
      Thank you.

    3. Phew! thanks for following up and letting me know about that. I am glad nothing seems to be broken after all.

      And Thanks for the kind words. Enjoy!

  12. Thanks for this beautiful Icon theme Rave, it looks incredible : )

    1. Thanks for your comment leo. It means a lot. We are glad you enjoy it.

  13. Hi guys, this is looking REALLY good! Thanks for all the hard work put into it!

    I just wanted to report a bug: On Ubuntu 15.04 with LibreOffice, the menu names disappear when clicked. (Screenshot:

    Thanks again!

  14. ¿Cuál debo descargar si tengo GTK 2?

    1. Hola Amigo. Yo recomendaría la versión 14.04 .

    2. Pero si está ejecutando ninguna aplicación gtk3 que necesita para que coincida con la versión gtk3 con construir aparece en cada versión.

      GTK2 construye son idénticos en todos los temas . Sólo los cambios gtk3 .

  15. Hi! The theme does not work on Mate with Compiz.

    Thank you and great work!

    1. That is very strange. It worked for me but I may not have the same version.

      What distro is this and what version?

      Sorry about that. Theme coding things change and no one tells us what they are changing and why we just have to go a figure everything out and why it's broken kinda sucks.

    2. Thanks for the follow up. I have started testing with that version. Hope I can come up with something.

  16. Exactly what I have been looking for. Thank you very much!

    1. And Thank you for your comment and support. Enjoy.

    2. This comment has been removed by the author.

  17. I am trying to make Compiz + Ambiance Flat Window Border work, but compiz always uses its own default one I think, and won't let me use custom. Anyone know a workaround? Thank you for this beautiful theme, Rave :*

    1. Sorry about that. I think this may be a issue in the config app. I will see what we can do. Is this on Ubuntu Mate?

    2. We have fixed this in 16.04. sorry about the issue.

  18. Nice theme. Zebra striping in tables would be awesome!

    1. I will see what we can do. And email you.

  19. Finally someone did it. A theme that looks fresh and new, but is based on Ambiance (meaning no graphical hiccups). You're awesome. Keep up the good work.

    1. Thanks for the kind words. A Ambiance base does work great. it's a very cleanly written theme and the code isn't a mess like some. It's having a few growing pains lately though that may prove a little hard to work through but we are going to do our best to do so. And I hope we can. Thanks again.

  20. This theme makes the "Weather Update" plug-in, on my Xfce desktop, be displayed with dark numbers and letters, instead of with light numbers and letters, like all the rest of the plug-ins and menus on my panel.

    I have, thought, the option to choose the colour of the letters and numbers displayed by my "Weather Update" plug-in.

    Which colour should I choose, then, for the numbers and letters of my "Weather Update" plug-in, for them to have the same (exact light grey) colour as all the rest of the numbers and letters in my panel?

    1. The Background color would be: #3A3A3A
      The Text or foreground color would be: #DFDFDF

    2. Ah, nice. :)

      Thank you very much for that information.

      Now, I can have my panel looking perfect. :)

  21. Hello! :)
    Thanks for your amazing theme. It's cool. But I have problem. Border from themes not work with MATE + Compiz. When I switch to Marco, it's good. But I can't use default window manager - I have problem with tearing on it. Can you rapair this to work with compiz?


    1. Hello. Thank you for the report about this. We will be doing our best to address this. I am not sure if this is a issue with way the toggling works in the new config panel or compiz has all of a sudden added new window border config requirements because ironically things used to work best with compiz.

    3. Hello
      On my Xubuntu 15.10 with compiz, gtk-window-decorator complains about theme descriptor file (I'm trying with Ambiance-Flat-Blue-Spring)
      Here's my error (in italian):

      Avviso del window manager: Caricamento del tema «Ambiance-Flat-Blue-Spring» non riuscito: Riga 389 carattere 82: L'elemento "shadow" non è consentito all'interno di "frame_style"

      The "shadow" element is not allowed in the "frame_style" element. Row 389 character 82

    4. Thanks Ivano. This is very helpful (It says exactly where the issue is). We have so much going on But I really want to get a patch out to 15.10. It's just we are in the middle of re-writieng the GTK 3 part of the theme from scratch for 16.04 so its hard for us to jump to alot of things. Hope to though.

    5. Ivano just a update we have updated and fixed this issue for the upcoming 16.04 theme. We where nervous about pushing a update to existing users on 15.10 because the fix removes some properties.

  22. Love your theme, but I have one question. Problem is in this picture Is it possible to change color of that "progress" bar to white? Sometimes it is hard to see what is the level of volume, because the color of progress bar and background is basically the same. I tried to change values of osd_colors in one of the .css files, but no luck. I use Cinnamon and Radiance-Flat-Blue theme. Thank you.

    1. Hi Denis so sorry about the delayed response we have been away developing lots of stuff in silence and meditation LOL! I believe that element you speak of is actually part of the cinnamon theme. you could try a few Cinnamon themes. We haven't really released a good one yet. We are working on doing so hopefully.

  23. Very nice theme but i have a problem in linux mint 17.2 and 17.3. The checkboxes are invisible. There is a way to fix that?

    thank you

  24. Replies
    1. glad you got it sorted. sorry if the versions are confusing.

  25. Hey. This is a wonderful theme, but ... I have a Linux Mint 17.3 Cinnamon. I noticed that these themes do not have a skin for the panel , but the "ambiance-colors" in harmony with the default Linux Mint panel, in difference from "ambiance-flat-colors", which I prefer. What should I do?

    1. Hello! Yeah sorry, unfortunately we did not get a chance to write a Flat-Colors Cinnamon theme. We are working on a new theme and hope to write one for that. It should be very similar so we can hopefully re-release that part separately.

  26. This comment has been removed by the author.

  27. Firstly, thank you for sharing this great theme.

    Could you tell if this theme works with gtk3 3.20 or not?
    I get the errors like below, when I start pasystray.

    (pasystray:927): Gtk-WARNING **: Theme parsing error: unity-greeter.css:59:22: The :focused pseudo-class is deprecated. Use :focus instead.

    (pasystray:927): Gtk-WARNING **: Theme parsing error: xfce.css:52:21: The '-gtk-image-effect' property has been renamed to '-gtk-icon-effect'

    1. Oh, it is in the description, sorry.
      It seems that all other themes from other designer are not working either.
      So far the theme that perfectly works is Adwaita which comes with XFCE4.
