Same headshot lighting for a doctor two very different looks

Starting a new position, Pranshu visited the JCP Home Studio in Albuquerque, New Mexico because as a doctor, he wanted a modern headshot for looking great on his new hospital’s website’s staff page. He had no preference to background color, so I suggested starting on a nice clean white background to standout on all website designs, and for the second headshot, switching to the bold look a black background makes, even with the same lighting on him for both shots. Which background color is your favorite?
