Matching flash-whitened foundation

A teenager in an emerald prom gown photographed with flash at the prom entrance, her face noticeably paler than her neck and chest.

Fictional demonstration. A prom photo taken with a phone flash at the venue entrance, where her foundation came out white against her neck.

Keep in mind: The new face color is matched to her neck and chest; it is not a measured record of her real skin tone. Only the skin color moved, so the eyelid makeup shifted warmer along with it.
