What does the blue color on the flag stand for?

The blue color on the flag symbolizes the Chief, specifically representing the Chief of the Navy or the naval leadership in general. In the context of military flags, colors are often imbued with specific meanings that reflect core values and attributes associated with the military branch. Blue is commonly associated with the qualities of vigilance, perseverance, and justice, which collectively highlight the essence of leadership in the armed forces. This interpretation aligns with the historical significance of the colors used in flags, where blue often conveys a sense of authority and stability, particularly in maritime services like the Navy.

While the other choices reference various virtues and attributes, they do not specifically align with the established meaning of the color blue in relation to naval symbolism. This reinforces the link between the color and its representation of leadership within the Navy.
