If you would like a custom color made leave me the RGB Values for it or if you do not have a specific RGB Value and just a Color Name that works too. I can change the outline colors of Neutral Camps and Friendly's as well

This changes the default outline around enemy troopers, guardians and players from red to yellow (more colors coming soon)

If you use a FPS Config, like optimization lock, you will need to edit it to see outlines again as most disable outlines to gain more fps

Look for these commands in gameinfo.gi and change them to what they are below!
"r_citadel_npr_outlines" "true"
"r_citadel_npr_outlines_max_dist" "1000"
"citadel_player_outline_enemies" "true"
"citadel_trooper_outline_enabled" "true"
"citadel_trooper_glow_disabled" "false"
"r_citadel_selection_outline2_alpha" "1"
"citadel_trooper_friendly_glow_disabled" "false"
r_citadel_npr_force_solid_outline           "true" 

citadel_boss_glow_disabled                  "1"              // Disables boss and walker glow/highlight effect. Set to "0" if you want Walkers to have outlines
