Dominic,

I tried to use a consistent color scheme based on the default plan that Simon included in the Beta, but found myself having inconsistencies and variations.  I tried to have colors for each use type, dark blue for broadcast, dark red for person to person, light green for marine, dark green for aviation.  I think your light blue was a better choice for marine.  Then I tried to have different colors for the different modes, CW, digital, voice, ...  Next I tried to make sure there was a noticeable change when one band plan transitioned to another.  I tried to avoid layering the band plans, but did it when I thought it was worthwhile, like showing the General class allowed ranges on  80, 40, and 20 Meter.  I just noticed that I missed 15M.  I also overlapped the ISM, WiFi and 13cm Ham bands.

I would be open to working with you and others to come up with a consistent color scheme and a more complete band and marker plan.
