This little snippet (courtesy of WordPress Code Snippets) allows you to color code the posts in your admin area, so that you can identify posts by their post status.
For example, in the snippet I have provided below, I have colored drafts in yellow, scheduled posts in green, private posts in red, posts that are pending review in blue and left all published posts as standard, with the alternating row colors.
This is useful for people who like to plan out their posts, because you can readily see how many posts are scheduled and ready, how many drafts you’ve got waiting to be finished, and if you’re an editor of a multi-contributor blog, you can see if you have any posts that need to be reviewed.
To enable this, copy the snippet below and paste it in your functions.php file (public_html/wp-content/themes/activetheme/functions.php). Obviously, if you want to customise it, you can change the colors using any CSS color declaration you choose.
