The callout during a TCAS warning that signals the AP/FD TCAS mode is armed is blue. This color-coded cue tells the crew that TCAS is in its armed state and ready to issue resolution advisories, with the autopilot/flight director prepared to respond if an RA is issued. It’s a quick, unambiguous way to confirm the integrated TCAS/autopilot configuration is active. The other phrases refer to different states or actions and do not indicate the armed status of TCAS.
