Princess Diana Bears a Striking Resemblance to Her Dad in Colorized Photo Released by Her Brother

Princess Diana was the spitting image of her father.

Royal fans were quick to notice the resemblance between the late mother of Prince William and Prince Harry when her brother, Charles Spencer, shared a rare photo of their late father, John Spencer, 8th Earl Spencer, as a young man.

“Thanks so much @marinamaral2 for turning one of my favourite black and white pictures of my father into this beautiful colour image,” wrote Charles on Twitter, adding that he looked forward to meeting the digital colorist later this year at the Althorp Literary Festival, which takes place at the historic family home where Diana is buried.

Amaral responded that it was a “huge honor!”

Diana inherited her dad’s blonde hair and bright blue eyes, traits easily missed in the original black and white portrait.

“He was: a gentle, kind, man without any pretentiousness,” Charles described his father in response to a follower’s comment on the image. “He was a loving father, and a man who enjoyed meeting people of every background. He treated everyone with great respect.”

Diana was the fourth of five children — but her brother, John, died in infancy. She had two older sisters, Sarah and Jane, and one younger brother, Charles, who is now the 9th Earl Spencer.

In 1969, when she was 7 years old, John and Diana’s mother, Frances, divorced. Her brother, Charles, told PEOPLE that the split, which saw her mother leaving the family home, was hard on her. “[It] was tough on Diana,” he said. “She used to sit on the doorstep at Park House and wait for her to come back.”
