Don,
I am not sure what industry you are in, but for Industrial Machinery, I know
of two standards addressing the use of red colored indicator lights. Hope
this helps:
EN 60204-1 - Safety of Machinery - Electrical equipment of machines, Part 1,
Table 3: Color for indicator lights and their meanings with respect to
condition of the machine. (Note: I have modified the layout in order to fit
into this email)
Colour: RED
Meaning: Emergency
Explanation: Hazardous condition
Action by operator: Immediate action to deal with hazardous condition (e.g.,
by operating emergency stop)
Examples of application: Pressure/temperature out of safe limits; Voltage
drop; Breakdown; Overtravel of a stop position.
NFPA 79 - Electrical Standard for Industry Machinery, Table 8 - Color coding
for pushbuttons, indicator (pilot) lights, and illuminated pushbuttons:
(Note: I have only included the Red color for indicator (pilot) lights and
again modified the format to fit into this email)
Color: RED
Device Type: Pilot Light
Typical Function: Danger or alarm, abnormal condition requiring immediate
attention
Examples: Indicatoin that a protective device has stopped the machine, e.g.,
overload
By the way, I don't interpret the above color code to be directly applicable
for visual display terminals, although I wouldn't put it pass third parties
to interpret it so.
Regards.
Tin

Does anyone know if there are any formal restrictions to using red
colored lights for front panel displays and indicators?
Is there a harmonized European standard or regulation or a specific
national regulation that requires the restriction of the color red for
warning, danger, etc.
It seems it may have been a German ergonomic requirement before various
standards were harmonized. Can anyone shed some light on this issue?
