This bug has persisted for roughly a month and seems to have not been reported on the forums from what I can find.
When using the default colours for enemy and teammate the “DETECTED” text is usaully red.
I have changed my enemy colour to purple and friendly to aqua. When using the custom colours I’ve noticed that the “DETECTED” text colour can vary from in different colours, most commonly red, white and even transparent.** The main issue being that transparent text is harder to notice in high-pressure situations.
I know this is only a minor bug, but would hope to see it fixed in a future update
