Christmas may be blue, but what's the spread on Hayley Williams' hair color that day?

It was a nearly bioluminescent red on Saturday (refer not to the photo but to the video below) when the precocious Paramore frontwoman -- accompanied by longtime boyfriend Chad Gilbert of New Found Glory -- performed a country-fried, acoustic rendition of 'Blue Christmas' at Kelly Clarkson's inaugural 'Miracle on Broadway' benefit concert in Nashville. The lineup also included bona fide country royalty like Reba McEntire and Garth Brooks putting their twangy spins on  holiday classics.

Williams -- a native of nearby Franklin, Tennessee -- performed the Elvis favorite with additional help from Josh Colbert of Further Seems Forever.

The $400,00 raised by the benefit will go to the Fruition Fund, which Clarkson through the Community Foundation of Middle Tennessee.
