What color is not authorized for JROTC socks?

In the context of JROTC uniforms, adherence to specific guidelines regarding attire is important for maintaining a standard appearance. The authorized colors for JROTC socks typically include options such as black or white, which align with the uniform's overall aesthetic requirements. Gray, however, does not conform to the established uniform guidelines and is not recognized as an acceptable color for socks in this setting. This is due to the emphasis on uniformity and professionalism within the JROTC program; having a standard color for socks helps ensure that all cadets present an organized and cohesive image. Therefore, gray is the color that is not authorized, as it deviates from these prescribed uniform standards.
