How to create custom admin color schemes in WordPress with wp_admin_css_color

The wp_admin_css_color function in WordPress is essentially a way to register a new color scheme for the admin interface. This function is part of the WordPress API and allows developers to customize the appearance of the admin dashboard by introducing new color schemes.

The color scheme can be applied on a per-user basis, meaning that each user can have their own unique color scheme for the admin interface. This can be particularly useful in multi-user environments, where individual users may prefer different color schemes for ease of use or aesthetic reasons.

It is also worth noting that the color scheme can be changed at any time, and the changes will be immediately reflected in the admin interface. This allows for dynamic customization of the admin dashboard, making it possible to change the color scheme based on specific conditions or events.

How to Add a Custom Admin Color Scheme in WordPress

The following code snippet shows how to use the wp_admin_css_color function to add a custom admin color scheme in WordPress.

function custom_admin_color_scheme() {
 $theme_name = 'My Custom Theme';
 $theme_url = get_stylesheet_directory_uri() . '/my-custom-theme.css';
 $theme_colors = array('#202020', '#ffffff', '#dfdfdf', '#464646');
 $theme_icons = array(
 'base' => '#202020',
 'focus' => '#ffffff',
 'current' => '#dfdfdf',
 );

 wp_admin_css_color('my_custom_theme', $theme_name, $theme_url, $theme_colors, $theme_icons);
}

add_action('admin_init', 'custom_admin_color_scheme');

This code defines a new admin color scheme called “My Custom Theme”. The colors and icons for the theme are defined by the $theme_colors and $theme_icons arrays respectively.
