Carl,

Before edm, I was using the VSystem display manager which handled the "no alarm" condition in a different manner than the EPICS display managers. As a result, I included
support for both behaviors. This is configured in the color file.

The following

alarm {
 disconnected : "white"
 invalid      : "med gold"
 minor        : "yellow"
 major        : "red"
 noalarm      : *
}

makes the "no alarm" color the color specified by the user.

Replacing the "*" with some color name, as in

alarm {
 disconnected : "white"
 invalid      : "med gold"
 minor        : "yellow"
 major        : "red"
 noalarm      : "green"
}

makes the "no alarm" color a fixed value.

I've always been under the impression that even if you check "alarm
sensitive" on the edm widgets, when the PV is in the no alarm condition the
color will be the foreground color configured for the widget.  Usually I
make this green so I don't test this much.  On my desktop installation, if I
make the foreground color something else like black, the text is black under
the no alarm severity, but goes yellow for minor, red for major.  In the ALS
control room edm installation, though, it changes the text color to green in
the no alarm condition regardless of the foreground color configuration.  Is
this an edm version difference, is there some display parameter its looking
at, or what?
