There are literally thousands of icon themes around for Your Linux desktop, but most of them are designed for GTK+ based desktop environments like Gnome, Cinnamon, MATE, Unity, XFCE, LXDE and more.
Few of the works well on Qt based desktops like KDE, LXQt or Lumina desktop, few looks horrible, but most of them lacks important icons for Qt based applications, mostly file manager navigation icons, action icons and MIME type icons.
Best LXQt or KDE icons
As both KDE and LXQt are based on Qt, any icon theme designed for KDE should also work fine with LXQt. That's also true for other Qt based applications, if a proper Qt theming tool like Qt5ct is used.
There's many icon theme, but choosing a proper one is important. Icons should be contrasting with the background color to make them clearly visible.
That's crucial for toolbar navigation icons and button icons, if these icons are not recognizable, then it kills the usability.
So, lets find out some pleasing LXQt/KDE icons that works well with Qt apps.
