Then it looks like I got it ... though you could have made it easier for people to understand your point. 😎

I don't think there are DBM-like Addons for GW2 (BlishHUD Timers is the closest I could find), but maybe ReShade could be used to emphasize the effect by boosting or modifying certain color values.

I think that this is an area where GW2 could still improve a lot. I wish it had more options to reduce visual clutter and less variety in how (important) visual cues look on the screen. It appears like developers have a lot of artistic freedom when they design those effects.
