Color markings on an instrument indicate what?

Color markings on an instrument are there to show the limits of what’s acceptable for that parameter. They mark the minimum and maximum values you should stay within, so you can tell at a glance whether the reading is within safe operating bounds or approaching a limit. This helps you quickly assess performance without calculating from the scale. They aren’t calibration constants, which would be fixed adjustments to the instrument’s readings, and they aren’t the exact alarm thresholds themselves, though moving into a marked zone may indicate you’re leaving the safe range and could trigger alarms.
