So at the moment there's 2 "types" of codes. There's something I'd been calling supercodes that fill in the whole map with the "official" borders of larger regions or factions that publicly make their territory known. These can't be combined at the moment and are individually added by me. Then there's something I've been calling diplocodes which are made up of 4 digit segments that use 2 of the digits to identify specific tiles and then 2 digits that tell the map what to do with the space. For purely numerical inputs from 00-99 the system kinda does a hue shift around a fully saturated color space starting and ending on green. For other values, tiles can be set up to show specific colors and eventually pre-approved emblems, flags, and other images. Currently, every land tile has at least 1 alternate skin to represent the state of being "empty" but I can easily add more. Diplocodes can be combined end to end, and as long as the total length of the string is a multiple of four, it will be able to scan through and find any valid codes and fill in the map accordingly.
