I didn't see anything in the instructions issued with ADE Alpha 17 about coloration of aprons, polygons, etc., so I thought I would express my findings.
The Raw Data View (Ctrl-Enter) includes a Coloration list which can be modified to set the color of aprons. Alpha is set to 255 for opaque. Since the aprons are different shades of gray, all the colors are usually set the same and can be set anywhere between 0 for black through 255 for white. ColorationOverrides must be set to True for it to take effect.
I'm not sure what the intention is for GroundMerging in the Flags list, but it is apparent that true causes the Bing imagery under the apron to cast discoloration to the apron making it look more realistic in my opinion. This seems to be the default for existing aprons at MSFS airports.
To make patches of different color shades on asphalt aprons, Taxi_Bitume is a good choice since it overlays the other surfaces and then can be color-adjusted in Raw Data View.
To access coloration for runways in Raw Data View, the Runway tree must be expanded to show other lists, including Coloration. Existing MSFS airport taxiways are made from aprons with links added for centerlines, taxi lights, etc., and aprons are also placed under runways. The Alpha setting can be changed from 255 to a lower number to add transparency without losing the runway markings. Various asphalt shades for the aprons under the runway will then show as runway patches that occur in real life.
Coloration changes are also useful in customizing scenery polygons.
I'm really enjoying what is possible in the developing ADE program.
