Which colors of earmuffs are authorized for wear in uniform?

The authorized colors of earmuffs for wear in uniform are black or navy blue. This aligns with the uniform regulations which aim to maintain a professional appearance while ensuring the functionality of equipment used in various operational environments.

The specific colors of black and navy blue are chosen as they provide a subdued appearance that complements military attire and avoids distracting from the uniform's overall presentation. In contrast, the other options feature colors that may not convey the same level of professionalism or might draw undue attention, making them less suitable for authorized wear with military uniforms.
