More like the pitch black outside your helmet, without even the stars you'd see in space...
All Battle armor have HUDs, which would likely be displaying Navigational data as long with info from the units sensors, and any other info the unit might be receiving like say the occasional navigation beacon, assuming there any in the area that are responding to you.
Not to mention the units head lights as well as Thermal and or low light sensors, I would also assume Radar/sonar would be in use, so say little of hydrophones.
Though It should be noted that 200m is not as dark as some would think, though AFAIK theirs little in the way of usable light at 200m, but it's only at 1,000m that is generally considered the pitch black zone.
