Lilac

Lilac, a Qt6 theme inspired by the Orchis GTK theme by Vinceliuice

About

A native Qt6 application style for KDE Plasma that provides modern widget styling without relying on Kvantum. This theme fully supports KDE color schemes, automatically adapting to your system colors.

This is strictly an application style - it handles only the appearance of Qt widgets and interface elements. It does not include icons, color schemes, or window decorations. Users are encouraged to pair it with their preferred color scheme, icon theme, window decorations…

Build Configuration

KStyle Integration

KStyle provides enhanced integration with KDE Plasma. If you dont use KStyle, QCommonStyle is used. You can configure its usage during build time:

• Default behavior: KStyle is a required dependency
• Available options:
  • -DNO_KSTYLE=ON: Doesn't use KStyle

Recommendation: Use KStyle with KDE Plasma, otherwise probably use QCommonStyle (KStyle has a lot of dependencies)

KColorScheme Support

KColorScheme extends QPalette functionality to provide better color consistency across KDE applications.

• Default behavior: KColorScheme is required dependency
• Available options:
  -DNO_KCOLORSCHEME=ON: Disables KColorScheme support

Note: KColorScheme is recommended for better color consistency, but can be disabled to reduce dependencies.
