如果你想在PHP中访问颜色，你必须做一些小技巧。在文件中，从toschos answer 他们使用全局变量$_wp_admin_css_colors. 这在运行时的任何时候都会被销毁。

实际上，我找到了正确的钩子来复制它：

<?php
    $admin_colors;
    add_action(\'admin_head\', function(){global $_wp_admin_css_colors; $admin_colors = $_wp_admin_css_colors;});
?>

$admin_colors[get_user_option(\'admin_color\')][\'colors\']; // array(0 => #222, 1 => #333, 2 => #0074a2, 3 => #2ea2cc)

$admin_colors = Array
(
    [fresh] => stdClass Object
    (
        [name] => Default
        [url] => https://example.com/wordpress/wp-admin/css/colors.min.css
        [colors] => Array
        (
            [0] => #222
            [1] => #333
            [2] => #0074a2
            [3] => #2ea2cc
        )
        [icon_colors] => Array
        (
            [base] => #999
            [focus] => #2ea2cc
            [current] => #fff
        )
    )
)

每个用户都可以设置自己的管理员配色方案，因此您也可以根据用户ID获取配色方案：

get_user_option( \'admin_color\', get_current_user_id() );

我认为这是获取或设置当前管理员配色方案的简单方法，请参见代码：

Set the default admin color scheme:

<?php

/**
 * Set the default admin color scheme for WordPress user.
 */
add_filter(\'get_user_option_admin_color\', \'set_default_admin_color\');
function set_default_admin_color($result)
{

    // set new default admin color scheme
    $result = \'midnight\';

    // return the new default color
    return $result;

}

/**
 * Get the current admin color scheme from WordPress user.
 */
add_filter(\'get_user_option_admin_color\', \'get_current_admin_color\');
function get_current_admin_color($result)
{

    global $_wp_admin_css_colors;

    // get current admin color scheme name
    $current_color_scheme = $result;

    // get all available colors from scheme name
    $colors = $_wp_admin_css_colors[$current_color_scheme];

    // now you can use this colors or store it
    // var_dump($colors);

    // important: we should return the default color scheme
    return $result;

 }

/**
 * Get all available admin colors schemes from WordPress user.
 */
add_filter(\'get_user_option_admin_color\', \'get_all_admin_colors\');
function get_all_admin_colors($result)
{

    global $_wp_admin_css_colors;

    // get all available color schemes
    $colors = $_wp_admin_css_colors;

    // now you can use this color schemes or store it
    // var_dump($colors);

    // important: we should return the default color scheme
    return $result;

}
