Different Coloros for different incident statuses



I need to have the next incident statuses:

- new

- pending

- solved

This is implemented in the plugin incident-status http://community.ushahidi.com/index.php/plugins/plugin/incident-status

My question is, how to create a different colors for different incident statuses on the main map ?

P.S. I read the developper guide, but I didn't find any Action or filter to huck this logic in the controller, who create and return an json for map..

Could I somewhere to overwrite this controller ? Or how I can do this ?
