NAKED blond ambition quashed Pam Anderson’s chance to star on “Desperate Houswives,” the former “Baywatch” babe says.

Anderson says she was offered the role of Susan Mayer – the accident-prone mom played to the hilt by Teri Hatcher – but producers wanted Pam to dye her blond hair brown for the part.

“Blond is my trademark, so I said no,” the 37-year-old former Playboy pinup told a reporter.

“Now I could kick myself as the show is simply great. I am hoping to persuade them to give me a guest-star role.”

Hatcher has been nominated for a Golden Globe (as Best Actress) for her work on the show – which is ABC’s biggest hit in years.
