You’ve temporarily changed your Facebook profile picture to the French tricolor in a sign of solidarity with the citizens of France — why not paint your nails blue, white and red, too?

Brooklyn-based company Duri Cosmetics has jumped on the tragedy bandwagon by promoting a range of Paris-themed products so “beauty mavens can unite and wave hands (and toes) in unity.”

In perhaps the most clueless p.r. stunt of the day, it distributed a gushing press release urging customers to buy three of its nail colors — “Baton Rouge Blue,” “I Do” (solid white) and “Parisian Tango” (red) — at $6 a pop, describing the gesture as an “effortless way to pay respects and show support.”

Trouble is, not a penny of the proceeds will help surviving victims of Friday’s massacre, which claimed the lives of 129 people in the French capital.

Asked by The Post if any of the profits would be donated, a Duri Cosmetics spokeswoman from Manhattan p.r. firm C.I. Visions said: “Unfortunately, they [Duri Cosmetics] had trouble getting a donation program with it.”

In the cringe-worthy press release, the company boasts how buyers can “offer a helping hand to Paris” with a “high ten” manicure customized with toxin-free, “chip-resistant, long-lasting nail polishes.”

New York p.r. veteran Rob DeRocker was appalled by the cynical publicity campaign.

“It’d be different if they were giving away the nail polish,” he told The Post. “It’s as if McDonald’s jumped on this to sell more French fries.”

Carol Ientile, of C.I Visions, the agency which put out the nail polish pitch, apologized Wednesday for the ill-judged marketing push, claiming it meant to be well-intentioned.

“I regret my missteps and any harm it has inflicted and take total ownership,” she wrote. “Duri had no part in my pitch efforts.”
