If you go to the help section (the question mark icon to the top right corner of the page you mention) and choose "GE rank values" you'll see that the GE implementations have different states. This help page takes you to this one: http://catalogue.fiware.org/content/help%23rank-values-description
where you have the info of the different "ranks" (statuses, if you like). The colour simply expresses the status in a visual way.
