Hi @berniinfante
What is this (I don’t understand why you have pasted this code):
<?php
do_action(‘acf/create_field’, array(
‘type’ => ‘checkbox’,
‘name’ => ‘white[hide_on_screen]‘,
‘value’ => $white['hide_on_screen'],
‘choices’ => array(
‘the_content’ => __(“<?php ?>”,’acf’),
‘excerpt’ => __(“Excerpt”),
‘custom_fields’ => __(“Custom Fields”),
… )
));
?>
As for you original question. Have you checked the page source (html) to actually see what is rendered. You may find that all you need to do is add a ‘#’ before the value for it to be a correct CSS color?
