Struct Theme 

pub struct Theme {

    pub primary: Color,
    pub secondary: Color,
    pub accent: Color,
    pub text: Color,
    pub text_dim: Color,
    pub border: Color,
    pub bg: Color,
    pub success: Color,
    pub warning: Color,
    pub error: Color,
    pub selected_bg: Color,
    pub selected_fg: Color,
    pub surface: Color,
    pub surface_hover: Color,
    pub surface_text: Color,
}

A color theme that flows through all widgets automatically.

Construct with Theme::dark() or Theme::light(), or build a custom theme by filling in the fields directly. Pass the theme via crate::RunConfig and every widget will pick up the colors without any extra wiring.

Fields

primary: Color

Primary accent color, used for focused borders and highlights.

secondary: Color

Secondary accent color, used for less prominent highlights.

accent: Color

Accent color for decorative elements.

text: Color

Default foreground text color.

text_dim: Color

Dimmed text color for secondary labels and hints.

border: Color

Border color for unfocused containers.

bg: Color

Background color. Typically Color::Reset to inherit the terminal background.

success: Color

Color for success states (e.g., toast notifications).

warning: Color

Color for warning states.

error: Color

Color for error states.

selected_bg: Color

Background color for selected list/table rows.

selected_fg: Color

Foreground color for selected list/table rows.

surface: Color

Subtle surface color for card backgrounds and elevated containers.

surface_hover: Color

Hover/active surface color, one step brighter than surface.

Used for interactive element hover states. Should be visually distinguishable from both surface and border.

surface_text: Color

Secondary text color guaranteed readable on surface backgrounds.

Use this instead of text_dim when rendering on surface-colored containers. text_dim is tuned for the main bg; on surface it may lack contrast.
