Which colors are shown on the master call panel lights?

• A. Pink/Red, Blue, Amber
• B. Green, Yellow, Orange
• C. White, Blue, Red
• D. Pink, White, Black

Answer: (A)

Signals on the master call panel are color-coded to show the priority and nature of alerts at a glance. The urgent warnings are indicated with a pinkish red, which stands out immediately and commands attention. A blue light typically marks a crew or cabin call, signaling that someone needs attention but not an immediate emergency. Amber (yellow-orange) is used for cautions or advisory conditions, indicating something to note without the immediacy of a warning.

This combination—pink/red for urgent warnings, blue for calls, and amber for cautions—fits how cockpit alerting is designed to be quickly distinguishable under various lighting conditions. Other color groupings like green, yellow, orange or white, black don’t align with the standard master call indicator scheme for these alert types, so they’re not correct for this panel.
