HUD Headshot Colour

I noticed this before the recent 1.1.3.0. blunder patch, the headshot HUD colour should be Lime Green as seen in the option screenshot & not the same as the enemy colour which is Pink.
This set of screenshots from in game were taken starting on 19th November Australian Time.

This picture below taken on the 19th Nov. shows Lime Green Head shot turning into Pink Head shot HUD display (taken from a video) in the very next couple of frames.

All my game video clips since this date(19th Nov.) are all Pink not Lime Green.
