Answer 1

In your second picture you can see that you are wearing the privateer suit. Now the privateer suit has the advantage that other privateers won't notice you. But there are still certain zones you can't go in. Those zones will be in red.

Now before you had the suit and you get quests, the zones will have different colors depending on what quest: Main quest, hunting quest, killing quest and the other one. It is still the same except some zones are in (red)zones you can't cross without being noticed you are not a privateer. And that is where the red zone comes in.

I can't find any resources to confirm this tho, but i'm wearing the privateer suit aswell in my game and I'll go check it out when i get home.
