For the background info, the priority icons are additional functionality for priorities.  The off-the-shelf custom fields don't have anything that can do it.  So you'd need the add-ons Mikael mentions.

You would need an app to do it. If you are using Jira Server have a look at Icons for Jira, Color custom fields, Rainbow just to name a few. If you go to the Marketplace you can find more.
