在我的网站上，我使用的是《创世纪》的子主题cenetric，这个主题附带了一些预定义的配色方案。
//* Add support for additional color style options
add_theme_support( \'genesis-style-selector\', array(
\'centric-pro-charcoal\' => __( \'Centric Charcoal\', \'centric\' ),
\'centric-pro-green\' => __( \'Centric Green\', \'centric\' ),
\'centric-pro-orange\' => __( \'Centric Orange\', \'centric\' ),
\'centric-pro-purple\' => __( \'Centric Purple\', \'centric\' ),
\'centric-pro-red\' => __( \'Centric Red\', \'centric\' ),
\'centric-pro-yellow\' => __( \'Centric Yellow\', \'centric\' ),
) );
现在，我正在寻找一种创建随机配色方案的方法，这样每次有用户访问我的网站时，配色方案都会自动选择。我尝试了以下方法：
$thm_out = array("Charcoal", "Green", "Orange", "Purple", "Red", "Yellow");
//* Add support for additional color style options
add_theme_support( \'genesis-style-selector\', array(
\'centric-pro-charcoal\' => __( \'Centric Charcoal\', \'centric\' ),
\'centric-pro-green\' => __( \'Centric Green\', \'centric\' ),
\'centric-pro-orange\' => __( \'Centric Orange\', \'centric\' ),
\'centric-pro-purple\' => __( \'Centric Purple\', \'centric\' ),
\'centric-pro-red\' => __( \'Centric Red\', \'centric\' ),
\'centric-pro-yellow\' => __( \'Centric Yellow\', \'centric\' ),
\'centric-pro-random\' => __( \'Centric \'.$thm_out[array_rand($thm_out, 2)].\'\', \'centric\' ),
) );
但它给我的管理面板以下错误，也不能正常工作。
Warning: Illegal offset type in C:\\xampp\\htdocs\\dev\\wp-content\\themes\\centric-pro\\functions.php on line 69
所以，你们能帮我解决这个问题吗？
