I'm not sure about the usefulness of their coloring scheme as there seems to be far too much green that isn't a park or public space. For example, I looked at my neighborhood and they have all the area around the on and off ramps of the local bypass colored green. Technically, yes, that area is all grass but I don't think coloring it green is useful.
