What color is secure voice mode described as?

Explanation:
Color cues are used to convey security status at a glance. Green is chosen for secure voice mode because it signals that everything is authorized and safe to use—encryption is active, the channel is authenticated, and confidentiality and integrity are assured. Red would indicate a problem or an insecure state, yellow often means degraded or cautionary status, and blue typically denotes a different condition depending on the system. So green best matches the idea of a fully secure, ready-to-use voice channel.
