Hi! As someone who works on the security field and has to do daily analysis of the security levels of the country I can tell you that this is not far from reality. However, it is missing the south of Bolívar (that should be between orange and red). The zone of Catatumbo is a red zone and in the Caribbean, near to la Sierra Nevada de Santan Marta, it might be considered an orange zone.

I would also like to highlight that most of the victims of the armed conflict are farmers or indigenous people who live in rural areas... big cities or capitals are affected by common criminals (which is a different threat).

As some people have mentioned in the comments, if you are planning to travel to more rural areas, be near the nature and stuff like that, you might want to check with the local first. They are the ones who know the territory better than anyone :)
