It is the responsibility of each transit agency to submit details of their services to Google, and that includes the various colours associated with routes. Different transit agencies use colours for various purposes. For example, my agency uses blue for regular routes, green for express routes and black for night routes.

You would have to contact your transit agency to confirm what the colours mean.
