Shedding a little light on the subject

 "... now it's getting really hard to tell who's who, even for me. Do you have any ideas on how to get the changelings to drop Sharp Wit's form?" the kelpie [ref: Riptide] grumbled.
[beginning query of possible detransmogrification triggers]

Primeval made and held eye contact for a moment, though there was barely a twitch in her already economical routine.

The kelpie did notice the cyborg twitch each time one of Sharp's doppelgangers cried out in pain using his voice.

The proto pony turned to face Riptide during a lull in the fight, "I believe I have an idea, one moment."

Riptide swept the remaining changelings away when the cyborg suddenly stopped moving and closed her eyes. It was not her imagination, the little cretins really were trying to stay out of her way... and that discovery left a nagging doubt in the back of her mind.

The kelpie was about to ask what was going on when Primeval opened her eyes again, a bright lavender light suffused them, seeming to flicker away, and then a moment later one of the gray changelings was limned in brilliant lavender light.

"I believe this will provide sufficient differentiation." The proto pony commented.
