I turned the Gas Planets in the None row into Hydrogen... but the conditions should maybe set to 0 for those. Otherwise, that chart is what I am using.
The fluorescence concern is valid, but it was up against being able to recognize the planet types by the icon... and muted colors quickly make them indistinguishable. Still, the "Brightness Offset Percent RGB" can be easily reduced in the XFileClasses_Stellar.txt to make them darker in the system map.
My main critique is that the portraits are a bit convex, mostly apparent in the Gas Planets which have the horizontal clouds. They could have been realistically mapped to spheres, but the effort involved was too great for the return, (the batch conversion for the current portraits "as is" took over 6 hours to run).
If it is feasible to host the textures, then maybe you should just make them available as one or more downloads at the mm page. That way with a couple beta data files and the "required" genesis map editor, people can give better thumbs up/down to all or some of the textures.
