As the guy behind the colour scheme, I personally use now light shade for autonomous area with a core outline on the borders of the country (including coastlines, not including borders of autonomous areas with other autonomous areas or core provinces). I think the scale of the map can come a bit short with outlines, so you can scrap that. I use the dark shade for territories of the core country or dominions, while the darkest colour corresponds to territories of the dominions. For military occuppied areas, the closest match refering to the way they are administered, would be a territory of the core country (dark colour), they are under no way autonomous (albeit I personally paint military occupation with the core colour, that is up to you to decide). I chose a dark blue colour for water so it can look better when combined with shoreline outlines in varying degrees of blue, aswell as reserving black for international borders, which opens a bigger array of grey-ish colours for n levels of internals. About the alternate colours for ideologies, I trend to use them, but it's not like they are really useful given said scenarios are rare. I recall there were other questions but I did the poll before starting to write and can't access them. Genius.
