Module swatch 

ColorSwatch — single clickable color cell with Role::ColorWell.

Public widget so apps can compose their own swatch rows or palettes outside of the bundled SwatchGrid. Renders an optional checkerboard underlay when color.a() < 1.0 so transparent swatches read correctly. The displayed color is a Prop<Color> — pass a static Color for a fixed palette entry or a Signal<Color> for a live preview that re-paints whenever the bound value changes (used by ColorPicker’s current-color preview and ColorEdit’s trigger swatch).

Accessibility

Declares Role::ColorWell; set_color_value carries the RGBA value and set_value carries the formatted hex string so braille and voice output both have a human-readable form. Selected swatches append a localized “selected” suffix to their announced name.

let _swatch = ColorSwatch::new(Color::new(0.21, 0.52, 0.89, 1.0))
    .size(24.0)
    .corner_radius(4.0);
