When loading a recently saved game (same game version) of a Heart of Gold campaign mission, the player color is changed from yellow to green. The load menu still shows a thumbnail of the map with yellow pixels for the player-owned areas, but as seen in the screenshot (level 3) after loading this is changed to green. Subsequent saves keep the green color.
I'm running build 1.6.66 of the GOG version (manual download) on Arch Linux.
