Ginnifer Goodwin debuts pastel hair at San Diego Comic-Con

SAN DIEGO, July 14 (UPI) -- Ginnifer Goodwin debuted pastel hair at San Diego Comic-Con.

The 37-year-old actress showed off her lilac locks at the Once Upon a Time panel, but told Us Weekly the change is only temporary and won't transfer to her character, Mary Margaret Blanchard, aka Snow White.

"[The color is just for me] in real life," she said. "Mary Margaret will still be brunette! I was copying my makeup artist. I was like, 'It's beautiful, I want that!' I've always loved gray, but I guess the key is lilac. It took eight hours of bleaching -- eight hours!"

Once Upon a Time subsequently shared photos of Goodwin and her co-stars at the panel on Twitter, including pictures of the actress and her husband, Josh Dallas, who portrays David Nolan, aka Prince Charming, on the series.
