PS4 controller flashing white red?

I'm currently playing through Red Dead Redemption 2 for the second time. I have now noticed that my controller flashes white and red alternately while I'm playing, does anyone know what that means?

Usually the following applies:

With multiple controllers - user 1 is blue, user 2 is red, user 3 is green, user 4 is pink
When the PS4 is idle and your controller is charging, it will be yellow
if you switch it on, it flashes white twice

However, some games also add extra features to the normal color coding of the PS4 controller. In Red Dead Redemption 2, the red and white glow seems to signal that bounty hunters are nearby, or at least in the area.

I already thought so, but I didn't even have a bounty in that area🤔
