If any group of people can help me with this interesting one it's you folks. So I hope most of you have seen that wonderful video of the ISS flyover of the Earth. In case you haven't for reference... Other than being blown away like everyone else something particular caught my eye, and after searching the web I found a list of the countries and discovered the interesting area was the country of Guatemala. If you watch closely around 1:26 when they fly over Guatemala the lights of the entire country appear green. You can almost trace the countries borders by following the green tinted area. This is most noticeable on the border with the very southern tip of Mexico where you can clearly see the bright orange city of Tapachula and the sliver of Mexico that extends the farthest south with this city included is clearly bright orange like the rest of the world from the video. To make it a little more intriguing it appears that the capital city of Guatemala is the ONLY part of the country that has bright orange lights like the rest of the world. Any insights would be helpful. Obviously, my first assumption was Guatemala uses a different kind of city light than...uhh, the rest of the world? Maybe Mercury or something, but no searches online appeared to confirm anything like that, and why the capital city wasn't converted when the rest of the country was makes it even a little stranger. Thanks a lot for any help.
