This utility plugin provides the ability to configure the color of the Admin Bar seen in the WordPress Dashboard and allows setting a message that will appear within the Admin Bar. This allows you to more easily identify when you’re working on Local, Staging and Live WordPress installations.
Usage Scenarios:
The Admin Color Bar plugin is useful when working with multiple installs of WordPress, such as when you have a local development environment, a staging site as well as a live site.
By setting the Admin Bar’s background color to Orange on a staging site, and Red for a local site, you can more easily identify which site you’re working on. This reduces the possibility that you’ll make errors by performing actions on the wrong site.
If you are using DesktopServer for your local development and would like to use the Admin Color Bar plugin as a Design Time plugin, you can install this in your /Applications/XAMPP/ds-plugins/ directory on Macintosh or the C:\xampplite\ds-plugins\ directory on Windows and it can then be configured to automatically start for all of your local development web sites. This allows you to use the plugin in your Local environment, where it’s needed and not to deploy it to your Live environment where it may not be needed. For more information on DesktopServer and local development tools, please visit our web site at: https://serverpress.com/get-desktopserver/
How it Works:
The plugin provides configuration options that allow you to select a background color and text color for the Admin Bar. You can also select a message that will be displayed within the Admin Bar to provide additional information to the users of the site.
The configuration settings will be seen by all users on the site. If you are using the plugin in a MultiSite environment, the settings are not shared among all the sites. You will need to configure each site on the network.

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
