This is an attempt to get a working Crystal icon theme for KDE Plasma 5, by combining/mixing different versions of the Crystal icon theme (that were created for KDE 3 desktop). Personally, I think Crystal is the best ever icon theme for the Linux desktop, and I'd like to be able to continue using it on my KDE Plasma 5 desktop.

Original author: Everaldo Coelho (
Adapted for KDE Plasma 5 by: Viet Dang (dangvd at

License: The original Crystal icon sets were licensed under the LGPL.

To install, unzip the .tar.gz file then copy the extracted Crystal Remix folder (e.g. crystal_remix-1.0-beta1 folder) to the system's icon themes folder (e.g. /usr/share/icons).

Note: you might have to refresh KDE Plasma 5 icon cache (e.g. running '$ rm ~/.cache/icon-cache.kcache') when you switch to using the new icon theme for the applications to refresh their icons.



The original posts from Everaldo are below, although the download links are no longer working:

However, the different Crystal icon sets can still be found online, for example:

Good job keeping Crystal alive!

Great work! Although, if my memory doesn't fail me, I remember some of the icons to be quite different, like the back/forward arrows for example. Would it be possible to take the originals as they were by default in KDE 3.5?

Thanks. About your point, there are a few versions of Crystal icon themes in the past, and the point of my project is not to replicate any one of them, but rather mix/enhance them in a way that looks better (in my personal taste) than the originals. With the back/forward arrows, I did try different alternatives and what I end up using is what I like the best. Also, in a few cases, I created my own derivative icons (for example, the email icon or the edit-select icon) to replace the originals.
