Hi. I’m new to FlightAware and don’t see the Q&A elsewhere. Various colors are used for the circle denoting an airport. For instance, this morning I’m seeing red for FOK, purple for MVY, orange for HYA, blue for PVD, and green for BOS. Where do I find info about these?
If MVY was purple I’m surprised you can see that as that would mean <1 mile visibility and/or <500 foot ceiling.
