Lightly is a fork of breeze theme style that aims to be visually modern and minimalistic.

Development ⚠️

Lightly is a work in progress theme, there is still a lot to change, so expect bugs! Some applications may suddenly crash or flicker.

If you have any feedback or encounter some bugs, feel free to open an issue or a pr.

Screenshots

With transparent dolphin view off and no sidebar transparency:

With a full glass color scheme (currently full glass color schemes are very buggy and not fully supported):

Configuration

Lightly configuration page can be found in the KDE system settings under the Application style section.

Most of these options are inherited from Breeze style, but Lightly has a few exclusive options that are enabled by default, including:

• Transparent Dolphin view (under the frames tab). This option disables the background and shadows of Dolphin view widget and draws top and bottom separators when the view has scrollable content.

• Sidebar opacity (under the transparency tab). By default, it's 60. If it's bellow 100, shadows will be drawn automatically.

The toolbar and menubar will follow the titlebar opacity. To configure the titlebar opacity, you will have to change the color scheme file directly in ~/.local/share/color-schemes. Open your desired color scheme and, in the [WM] section, add a fourth value to activeBackground and inactiveBackground, like activeBackground=0,0,0,127 where the last value is the alpha, that ranges from 0 (completely transparent) to 255 (totally opaque).
