I am using a custom workflow with Jira Agile 6.3.1. I have a total of 11 columns with the appropriate statuses mapped out, as shown below.

How can I configure the colour coding of the columns? The red-yellow-green is reflected as a summary on the sprint planning view, but currently this means that an issue will only be marked as done when it is released into production, not when it has passed testing and is ready for release. This means that the red-yellow-green status is next to useless, as almost every ticket will be In Progress (see below):

In this case, we are one day away from the end of our sprint, and nearly every issue has passed testing and is ready for release, which in our book counts as done - but Jira Agile doesn't agree!
