Override per environment in config/cast.php:

PHP

return [
    'buttonColor' => 'red',
    'defaultTheme' => 'auto',
    'allowUserOverride' => true,
    'enabledThemes' => ['dark', 'high-contrast'],
    'autoLightTheme' => '',
    'autoDarkTheme' => 'dark',
    'themesPath' => '@root/cast-themes',
];

An empty handle means Craft's stock appearance. Copy src/config.php for a commented starting point.
