Define colour of swimlanes in Jira Agile

I would like to define a user defined colour to each swimlane within JIRA Agile (including the background if possible). This should not be dependant on any query or ticket type. This should be a freely definable colour.

The idea behind this is to create a better over view of the stories within a sprint. Please see the attached screenshot of how we do this in our "non-digital" board which we of course want to replace with JIRA Agile.

Please see the screen shot attached for how we currently work and what require of JIRA Agile.

Thanks in advance and keep up the good work.
