Crate redbear_tui_theme 

Red Bear OS — default TUI skin palette.

Single source of truth for the Red Bear brand colours used by every TUI application on Red Bear OS (tlc, cub, redbear-info, redbear-netctl-console, redbear-wifictl, redbear-btctl, the redbear-mtr family, redbear-hwutils, and any future TUI).

See local/docs/RED-BEAR-TUI-THEME.md for the design rationale, WCAG contrast ratios, and migration plan.

The palette is deliberately ratatui-free at this layer. Apps that want a ratatui::style::Color from a slot do a single one-line conversion: Color::Rgb(t.background.0, t.background.1, t.background.2). Keeping this crate free of ratatui means non-ratatui TUI libs (cursive, termion-direct, etc.) can also consume the palette.

Example

use redbear_tui_theme::REDBEAR_DARK;

// Render a selection row in a TUI list.
let bg = REDBEAR_DARK.selection_bg;
let fg = REDBEAR_DARK.selection_fg;
assert_eq!((bg.0, bg.1, bg.2), (0x36, 0x52, 0xA0));
assert_eq!((fg.0, fg.1, fg.2), (0xF4, 0xF4, 0xF4));

Brand red

The accent colour #B52430 is the same red used by cub’s already-shipped RedBearTheme and by the Red Bear OS brand assets (local/Assets/images/Red Bear OS icon.png and the loading background). It is byte-identical in both the dark and light themes; only the background flips.

Modules

fallback

Terminal-fallback colour resolution.

Structs

Rgb

A 24-bit RGB colour. Deliberately not a re-export of ratatui::style::Color::Rgb so this crate stays free of any TUI library dependency.

Theme

A complete color theme. All slots are truecolor Rgb(u8, u8, u8).

Constants

REDBEAR_DARK

The default dark theme. All foreground/background pairs in this theme pass WCAG 2.1 AA-body (4.5:1) except dim and border is tuned to AA-body, and the dim/hidden slot which is intentionally 2.9:1 for de-emphasis.

REDBEAR_LIGHT

The light theme. Brand red is identical to the dark theme — only the background flips. See REDBEAR_DARK for the slot semantics.
