Royal blue, named after Queen Charlotte in the late 18th century, was originally a deep, vivid hue reserved for the aristocracy. It symbolized significance and prestige. Over time, however, the color's perception shifted. By the 1950s, a brighter version gained favor, culminating in standardizing a luminous shade as 'royalblue' in the digital age (1987). This choice by the World Wide Web Consortium highlights the color's adaptability, evolving alongside societal preferences and technological advancements.
