The answer is: Blue and white

Esther 8:15

In the Book of Esther, we see Mordecai donning royal apparel of blue and white—these colors aren't just fashionable choices, they carry rich symbolism. Blue is often associated with divinity and transcendence in biblical texts, representing the heavens and God's commands. White, symbolizing purity and righteousness, stands in stark contrast to the darker narrative points of the story.

Interestingly, Mordecai's elevation to a position of power comes in the aftermath of a perilous plot against the Jewish people, as orchestrated by Haman. His royal apparel signifies not just his newfound status, but it also vividly marks the dramatic turning of events from oppression to empowerment, showcasing the theme of reversal that runs deep in Esther. This transformation is reminiscent of other biblical stories where figures are elevated after times of suffering—think of Joseph from the pit to the palace.

Moreover, Mordecai's attire can remind us of the garments of righteousness portrayed in various scriptures. The idea that what we wear reflects internal disposition is mirrored in passages like Isaiah 61:10, where garments of salvation and robes of righteousness are abundant.

So, while Mordecai walks through the city dressed in resplendent blue and white, cheering crowds around him celebrate not just the man, but the profound lessons of courage, resilience, and hope that his story embodies—a testament to the worthy struggle for justice and the taming of relentless fate!
