Robert,
In the industrial world these are the expected colours for pilot
lights (based on EN 60204-1. BTW, the same colours are used in ANSI/
NFPA 79):
Colour Meaning Explanation
Action by operator
RED Emergency Hazardous Condition
Immediate action to deal with
the hazardous condition (e.g. By operating the e-stop)
AMBER/Yellow Abnormal Abnormal condition,
Monitoring and/or
intervention
impending
critical condition
GREEN Normal Normal condition
Optional - no action required
BLUE Mandatory Indication of a condition that
Mandatory action
requires action
by the
operator
WHITE Neutral Other conditions. May be
Monitoring
used when there
is doubt
about the
application of
RED,
YELLOW,GREEN,
BLUE
Based on 'normal' Western expectations, an orange light would be more
likely to be a warning than a normal condition. If this is a consumer
product, consider the basic traffic light, recognizing that it sets
the expectations for most people. Orange is pretty close to Yellow or
Amber.
Just my two cents...
