Struct Theme 

pub struct Theme {

    pub border_focused: Style,
    pub border_unfocused: Style,
    pub border_popup: Style,
    pub border_error: Style,
    pub border_warning: Style,
    pub tab_active: Style,
    pub tab_inactive: Style,
    pub selection: Style,
    pub shortcut_key: Style,
    pub shortcut_indicator: Style,
    pub section_header: Style,
    pub body: Style,
    pub hint: Style,
    pub separator: Style,
    pub success: Style,
}

Color and style palette for tui-kit components.

Usage

Use Theme::native() (the default) for a palette that adapts to the user’s terminal color scheme, or Theme::dark() for a fixed lazygit-inspired dark palette.

Extending for your app

Wrap Theme in your own struct for app-specific semantic roles:

pub struct AppTheme {
    pub base: Theme,            // passed to all tui-kit calls
    pub my_semantic: Style,     // app-specific roles
}

impl AppTheme {
    pub fn native() -> Self {
        Self {
            base: Theme::native(),
            my_semantic: Style::default().fg(Color::LightGreen),
        }
    }
}

Theme is Copy so it is cheap to pass by value or reference.

Implementations

impl Theme

pub fn native() -> Self

16-color native palette — adapts to the user’s terminal color scheme.

Uses only the 16 named ANSI colors so the result respects the terminal theme (dark/light, Solarized, Nord, etc.).

Role	Color
Accent / focused	LightBlue
Tabs / headers	LightBlue
Shortcuts	Yellow
Selection	Black on LightBlue
Positive signal	LightGreen
Negative signal	LightRed
Muted / hints	DarkGray

pub fn dark() -> Self

Fixed dark palette with green accents — does not adapt to terminal theme.

Use when you know the terminal has a dark background and want a consistent lazygit-inspired look regardless of terminal settings.

Role	Color
Accent / focused	Green + Bold
Unfocused border	White
Active tab	Green + Bold
Selection	White on Blue + Bold
Shortcut keys	Yellow
Section headers	Cyan + Bold
Hints	DarkGray
