Kate Middleton took over as Colonel of the Irish Guards from her husband Prince William.

During the St. Patrick's Day parade, Kate took the salute and handed out shamrocks.

A body language expert said Kate wore her "superhero color"—red, blue, or turquoise—to assert her control over William and guests.

Kate appeared very confident and walked upright during the parade.

William seemed more reserved in his approach, possibly to not overshadow his wife.

Kate leaned down to meet the eye level of guests to make them feel at ease.

The fact that Kate considered someone else's viewpoint shows why she is great at communicating with the public.

Kate and William have both grown in confidence and elegance over the years.

The couple continues to conduct themselves well in public appearances.
