ZetosI'm not sure about this one, but probably the PlayerHealthBGBonus color is already set inside Resource/HUDPlayerHealth. You can try this route.
Well, that didn't quite seem to do the trick either. I appreciate your help though. When I look at HUDPlayerHealth, "PlayerStatusHealthBonusImage" points to an image "replay/thumbnails/buff". Would that be what's setting the colour?
