Aerotower
I've asked AirNav if they can give me a list of colour $TYPE numbers for the categories in Colour Preferences, and they say they don't know/ can't match them.
This is the list of colours that I use. It's compatible with the high-res outlines produced elsewhere:
1 - white
2 - basic outline
3 - coastline
25 - water
26 - red
27 - runway centreline
28 - grass
29 - buildings
30 - general airport markings / dirt runway boundaries
