WP Term Colors

I needed to save colors for terms, and found that @jjj had already done the work. Accessing the saved colors is pretty straightforward using the new (WP 4.4 or newer) built-in utility function:
$color = get_term_meta( $term_id, 'color', true );
The terms are saved in hex format (#eeee22) so are ready to use once retrieved.
Thanks @jjj.



Works well with WP's new termmeta table
