Pamela Anderson is living la dolce vita in every color of the rainbow.

The 59-year-old actress has been on a technicolor tear at the 83rd Venice Film Festival, where she’s promoting her new film “Place to Be.”

Since Friday, she’s served up four looks in as many days across cocktail parties, gala carpets and photo ops, making waves on the Lido at every turn.

The “Last Showgirl” star kicked things off Friday at the Golden Globes x Aman Beverly Hills Cocktail Party in a coral pink caped Oscar de la Renta gown ($5,990), adorned with a bejeweled hibiscus brooch at the shoulder.

Hairstylist John Nollet styled her platinum blond hair in bouncy, bed-head curls for the occasion, complementing her signature fresh-faced and makeup-free look.

She turned up the wattage Sunday at the amfAR Gala Venezia, arriving in a custom Calvin Klein Collection gown in bright pumpkin orange with a matching satin sash draped over her arms.

White pointed pumps, an armful of bracelets and soft Old Hollywood curls completed the look for the benefit, which raises funds for AIDS research.

Anderson accepted the nonprofit’s Award of Courage at Sunday’s event, where she reflected on her hepatitis C diagnosis in the late 1990s.

“It was a death sentence,” the “Baywatch” alum told the crowd, per Variety, recalling that her doctor said she “probably had around 10 years to live.”

On Monday, the “Baywatch” alum made an unexpected pivot into sharply tailored black and white earlier in the day, wearing an Elisabetta Franchi suit and ruffled white shirt that Karl Lagerfeld surely would have approved of.

She styled the look with black Santoni pumps and dark sunglasses as she left the Hotel Excelsior.

Anderson returned to vivid color later that day for the Golden Lion opening ceremony, stepping onto the pier in head-to-toe Carolina Herrera: a column skirt, billowy chiffon top, and matching Consuelo leather clutch ($1,690). Cat-eye tortoiseshell sunglasses and cheetah-print pumps finished off the ensemble.

Anderson plays the daughter of “The Exorcist” star Ellen Burstyn in “Place to Be,” a road-trip film that also stars Taika Waititi.

Burstyn, 93, was honored with the Golden Lion for Lifetime Achievement at Monday’s opening ceremony.
