Dwight, Check out GR-2914 "Human Factors Requirements for Equipment to Improve Network Reliability" section 4.2.4 "Color Requirements for Alarms".
For product intended for the EU, check out EN60950 section 1.7.8.2 "Colours" and the referenced document IEC-73 "Basic and safety principles for man-machine interface, marking and identification ..." section 4.2.1.1.

I recall a Bellcore spec that says we have to do this. Can anyone help me track down the spec reference for this? thanks Dwight ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
