The British Royal Family’s frequent use of blue has led to this shade being colloquially known as "royal blue." This tradition was recently highlighted on 3/12 when Princess Kate Middleton attended a reception for German President Frank-Walter Steinmeier at Windsor Castle. She garnered attention wearing a blue sequined dress, a matching cloak, and the Oriental Circlet, the largest tiara she has used to date.

Princess Kate, much like other British royals, often incorporates blue into her wardrobe, featuring a spectrum of tones from soft pastels to deep navy. This preference is evident in various family moments: the Christmas 2022 card showed Prince William and his children dressed in blue, strolling through a village. For his 5th birthday, Prince Louis wore a Fair Isle sweater, smiling happily in a wheelbarrow. Princess Charlotte has also appeared in blue dresses for numerous birthdays, family photographs, and public events.

According to Vogue, the royals' choice of blue is not accidental; it conveys significant meaning. The Princess of Wales is considered a master of visual communication, often delivering subtle messages through her expressions or attire. Elizabeth Holmes, author of the New York Times bestseller, *HRH: So Many Thoughts on Royal Style*, told Vogue that wearing this shade subtly expresses patriotism, as blue is one of the colors on the British flag.

The color, initially developed for a Queen Charlotte dress design competition in the 1800s, later became a traditional color for the British Royal Family. Each time family members appear in this shade, they evoke a sense of family unity and national pride.

Doctor Sarah Seung-McFarland, an American psychologist, notes that blue offers several advantages for the royal family. She told Marie Claire that the color is "associated with trust, responsibility, authority, competence, and contemplation — qualities important for those in royal positions." Blue also possesses a calming, peaceful effect, making it suitable for those wishing to connect with the public.

Beyond important occasions, blue is strategically used to provide reassurance during periods of family, societal, or national instability. It reminds people of the commitment and duty the monarchy is meant to represent. Sarah stated, "It's a way to bring peace amidst much change."

In 2020, Princess Kate wore blue more frequently as the world grappled with Covid-19. Like the late Queen, she carefully considers her fashion choices. According to Hello magazine, her and her family's decision to wear blue during lockdown served as a profound tribute to frontline workers battling the pandemic.

The British Royal Family's consistent choice of blue is not merely a tradition; it is a style strategy refined over decades. For Princess Kate Middleton, blue has become a fashion language, affirming her composure and dedication to service. This blue simultaneously suggests royalty and highlights her refined, public-facing image.

By maintaining a color palette linked to history while updating contemporary silhouettes and materials, the royals demonstrate that their fashion can be dignified yet approachable, iconic yet current. Vogue suggests this approach elevates the image of the British Royal Family as an institution that preserves core values while embracing innovation. Through color, their soft power is reinforced.
