KvDark is a dark Kvantum theme (kde-look.org/content/show.php/…) for KDE plus an Arorae decoration, a Plasma theme and a matching GTK2 theme.
My goal was to make a photorealistic dark theme for KDE but the current Qt theme engines weren't flexible enough. So, I made "Kvantum", with which it was possible to create what I had in mind. Kvantum has its own default theme too, which is inspired by the default theme of Enlightenment.
NOTE: KvDark and KvDarkRed are among Kvantum's extra themes now. Please delete the user installations of these themes and USE THE THEMES THAT COME WITH KVANTUM instead!

* Rounded progress bars (which need Kvantum >= 0.8.19).
* Tweaked sliders.
* A bit milder gradient for toolbars.
* Header separators (needs Kvantum >= 0.8.20).
* Added a variant with some red elements (KvDarkRed).
BTW, don't use KvDark from here! Remove it with Kvantum Manager and use the one that comes with Kvantum. I've included several high quality themes in recent versions of Kvantum.
