    It is usually most important to set the default value of the setting as well as its sanitization callback, which will ensure that no unsafe data is stored in the database.

    $wp_customize->add_setting( 'accent_color', array(
  'default' => '#f72525',
  'sanitize_callback' => 'sanitize_hex_color',
) );
