[pokeemerald] What is the purpose of secondary overworld palettes?

[Soilydude]

I've been messing around with the palettes in the decompilation to try and add more "lit up" elements to the day/night system I'm using. It's going pretty well but I'm having a nightmare working out which colours and palettes I can swap etc.

One thing I can't quite get my head around is the purpose of the secondary palettes found in "data/tilesets/secondary/[LOCATION]/palettes". Editing these doesn't seem to do anything as far as I can tell, and all overworld areas seem to use the palettes stored in "data/tilesets/primary/general". I was hoping each area would have its own set of palettes so there'd be more freedom in switching up colours, but this doesn't seem to be the case - though I'm not sure if this could be a consequence of the day/night system I'm using, or related to how Porymap handles palettes.

Can anyone shed some light on this? Also if there's any good resource out there which details how the colours, palettes, and tilesets systems interact with each other, I'd really appreciate that as I feel like I'm only halfway there with my understanding.

Thanks!

The point of secondary palettes is to allow secondary tilesets to use colors that aren't present in the palette of the primary tileset.

When the game loads the tilesets for a map, it loads palettes 0-5 from the primary tileset and palettes 6-12 from the secondary tileset.
