With five days of New York Fashion Week under our belts, it's safe to say we've seen a lot of hair and makeup, but the coolest hair we've seen so far was, without a doubt, the blue and orange-streaked ponytails at Saturday's Herve Leger show.

Our roving photographer went backstage to capture the models getting ready for the show, which included blue and orange extensions to add to their locks. Click through the gallery above to see our latest source of hair color inspiration.
