Iinntteerreessttiinngg - I have done quite a few planet-side ops, and NEVER seen any red exclusion zone - just find it by tripping it.
It may be that I'm red/green colour blind (mild) so red is a very dull colour and blue is a very bright colour...
Could you give me a hint where to find the System Colour selector to make it easier for me to see things like trip wires :-}
TIA Mijk
There's a link to the HUD customization tool in post #9 of this thread. Also in that post a link to a Reddit post which has examples of different colored themes that can be helpful to get started.
It only works if you are playing on PC. If you are on a console, I don't believe there is a way to change the HUD color scheme at this time.
