“In royal protocol, clothes are a form of silent communication. Red provides high visibility in crowds, honors host nation flag colors, and conveys confidence during state occasions.”

Visibility for Crowds: As Queen Elizabeth II famously noted, royal figures must be seen to be believed. Bright primary colors ensure that members of the public standing in large crowds can spot the royal figure from a distance.
-
National and State Symbolism: Red is a primary color in the flags of many Commonwealth nations (such as Canada) and host countries. Royal figures frequently wear red on official foreign tours or state receptions as a gesture of diplomatic respect.

Historical Tradition: Both Catherine, Princess of Wales, and Meghan, Duchess of Sussex, have worn red for major formal occasions—from state banquets and Remembrance ceremonies to high-profile galas—following a tradition that dates back centuries.
