No. The original scheme had autonomous areas (the dominions) as a darker colour. Lighter shades were introduced for protectorates/protected states which are not autonomous areas within an entity, but separate countries where external influence on the functioning of government and some domestic and foreign policy is formalized via treaty (an example sticking with the British Empire would be the Trucial States or Trucial Oman) unlike say the informal influence which is shown via filling in a country with the influencing country's colour but keeping the influenced country's colour as a outline showing formally full sovereignty (example using the British Empire would be (non-Trucial) Oman)yeah probably, and same with china
Which maps are you referring to specifically? I use a wide variety of sources, including books, scholarly articles, wikipedia, baidu, the worldstatesmen.org database, etc.
You're right. We need to edit those maps.This is my first time posting on here, so forgive me I'm doing something wrong, but I think there's an error within the region of Arabia in the maps from 1748 to 1815; while the emirates of the UAE are independent, but Oman is seen holding the areas around the UAE for an entire century, before a state (which I'm assuming is the Trucial States) shows up in 1848.
