How to get the value from category color picker field for single post excerpts displayed on home page.
Something like this but in the home.php loop to style post excerpts based on the value added via the Edit Category field using color picker. https://www.advancedcustomfields.com/resources/adding-fields-taxonomy-term/
In the loop over the posts you must get the post category and then get the field from that category.
while(have_posts()) {
the_post();
$categories = wp_get_post_categories($post->ID);
$color = get_field('color_field_name', $categories[0]);
}
