The Queen, Camilla, Princess Anne and other members of the royal family wore matching green in a final tribute to Prince Philip as they attended a memorial service in his honour.
The royal women were united in the same shade, the Duke of Edinburgh's official dark green livery colour was known as Edinburgh Green.
It was used for his staff liveries – the duke’s page at the coronation wore dark green and silver – and private cars.
Others in the congregation also wore dark green, including Duke of Edinburgh Gold Award holder Doyin Sonibare, who delivered a special tribute about the effect Philip’s youth scheme had on her life.
The Queen teamed her dark green coat with a brooch that was also a nod to her "strength and stay", who passed away in April last year.
She chose her yellow gold, ruby and diamond scarab brooch, designed by Andrew Grima, which was a personal gift from Philip in 1966.
Camilla wore her Rifles brooch in recognition of the moment when her father-in-law handed over his role as colonel-in-chief of the regiment to her in 2020.
Meanwhile members of the late royal's staff wore matching green and white striped ties, which was designed by the Duke for his employees to wear while in his service.
Speaking to Sky News, his former personal protection officer Richard Griffin explained: "This this is a tie Prince Philip designed so anyone who worked for his personal household, this is the tie they all wore.
"When the service came out we've all been going through our wardrobes trying to find this tie."
However not all guests opted for green, with many of the younger royal women deciding to dress in green.
The Duchess of Cambridge wore for a high-necked black dress with white polka dots and a textured wide-brimmed black hat.
Sophie Wessex and Philip's granddaughter Princess Beatrice, who burst into tears during the moving ceremony, also went for black outfits for the occasion.
Prince George matched his dad in a smart blue suit and tie, while Princess Charlotte and her second-cousin Mia Tindal wore formal navy coats.
