We are charmed by this photo of Mrs. O, taken on the campaign trail last October in Boulder, Colorado. The vibrant red provides a great punch of color and the asymmetrical neckline of her top gives a modern twist to a traditional sweater set. Her signature style brooch layers more red-the color of passion and heart-onto this ensemble.

Many previous First Ladies have enjoyed the color red in the past. The Heart Truth's First Lady Dress Collection showcases seven different bold-hued outfits once worn by a variety of First Ladies. The collection, which helps boost the public's awareness of the number one killer of women: heart disease, is currently on view for the third time at The National First Ladies Library in Canton, Ohio. (Previous viewings were in 2005 at the John F. Kennedy Center for the Performing Arts and in 2007 at the Ronald Reagan Presidential Library and Museum.)

Evening gowns on display include a pleated Mary McFadden dress from Claudia (Lady Bird) Johnson, a chiffon Valentino design worn from Nancy Reagan, a gold-trimmed gown by Arnold Scassi from Barbara Bush, and a sequined Oscar de la Renta design from Laura Bush.

Daytime looks include a cashmere dress by Cliff Chally from Hillary Clinton and a crepe suit by Neiman Marcus from Betty Ford. And, although not included in this collection, Jacqueline Kennedy-who tended towards wearing white or pastel colors-donned a cherry red dress at a White House Christmas party in 1961.

Mrs. O loves purple, as we know, and she looks fantastic in various shades of blue. But she has also shown a fondness for red (her red and black Narcisco Rodriguez dress in Grant Park on election night, her coral red sheath by Maria Pinto when she went to meet the Bushes at the White House). So we expect to see more of her in this popular First Lady hue.
