The answer is: Blue and white

Esther 8:15

When Mordecai donned his royal apparel of blue and white, he wasn't just putting on fancy clothes; he was embracing a new status and symbolizing triumph over adversity. In the story of Esther, Mordecai goes from sitting at the city gate to being second in command to King Ahasuerus after successfully thwarting a plot against the Jewish people. Blue often represents divinity or heavenly grace, while white can signify purity and righteousness. Together, they reflect a moment of divine favor.

But let’s not stop there! Roman historical accounts and even some archaeological finds show that blue was considered the color of royalty and power. In ancient times, it took a lot of resources to dye fabrics blue, making it a scarce and coveted color. White also has deep meanings in many cultures, often associated with light, clarity, and new beginnings.

What’s also interesting is that this transition correlates with themes of identity and fate echoing through literature and mythology; like Joseph in Genesis, who put on his "best garments" upon being promoted, Mordecai represents restoration and recognition after endurance.

In fact, the communicated importance of clothing in the scriptures spans many styles and colors, crafting a rich tapestry of meaning throughout biblical narratives. So next time we think of royal attire in the Bible, remember Mordecai and celebrate the ultimate turnabout—from oppression to exaltation—in the colorful fabric of faith.
