In general terms, yellow = awesome, red = great and orange = nice, all from a motorcycling perspective. The maps themselves don't offer a lot of navigational detail but used in conjunction with a AAA map, good road atlas or some other more highly detailed map they are a great way to plan out a ride. I usually consult the Butler map for ideas and then plot out routes on pages that I cut out of my CA road atlas, which I then fold and stick in the window of my tank bag.
