Kate Middleton shows off brand new hair colour

She’s got one of the most famous manes in the world, and the Duchess of Cambridge has just stepped out with a brand new style.

Kate Middleton has undergone a bit of a hair makeover.

The Duchess of Cambridge, 37, debuted a much lighter hairstyle on Wednesday during a visit to the Natural History Museum in London.

The royal was, as always, immaculately dressed for the occasion, wearing a pair of khaki Jigsaw culottes with a burgundy Warehouse jumper and a Chanel bag.

Kate’s visit to the museum was designed to shine a spotlight on the Angela Marmont Centre, which is dedicated to the study of the natural world.

Over the past few years, Kate’s world-famous hair has maintained a darker brunette shade, but she recently made the decision to switch to a more golden hue in time for the British autumn.

Just last month, Kate showed off the result of a new hair cut while taking Princess Charlotte, 4, to school for the first time.

Her traditionally longer locks were cut into a shorter, bouncier style.
