Set the outline color on the entity which has the badger:presentation_event component.
Example:
"on_lured": {
"outline": {
"color": 4, // an index into the outline colors array defined in PostFX.dragonfx (0 = None, 1 = Teammate, 2 = Enemy, 3 = Directed, 4 = Lured)
"duration": 2.0 // the seconds to display the outline for before it disappears (don't define this field, or set it to -1.0 to make it last forever)
}
}
