Hello, yes these are established Trails as part of the Legacy trail system. This trail system is in the developmental process. It used to be a state-owned psychiatric facility. So some of the trails are loosely yet unofficially named and color coded at this time. This is a project that's in the works and being mapped out with the township. So, a lot of it is word of mouth amongst trail users at this time. But some of the markers are coordinating with established colors given for each section of the trail. I hope that helps. I am new to using the open street map system. But I have been utilizing it to try to help users identify different parts of the trail system.
