A few months ago I posted the following message:
---
"During the design-phase of SCADA-applications there sometimes is confusion about the status of the symbols (e.g. valves, pumps etc.) and their color.
There is no HMI standard regarding symbol color that I am aware of. There does seem to be industry specific guidelines, however. Some industries like red to be the energized/on state, others use green for the same condition and so on.
Is there a HMI standard regarding symbol color or is there a report where the topic of symbol color is addressed?"

Your reactions were very interesting and helpful. The subject 'Symbol Colors' started a good debate on Control.com.
I'm at this moment busy developing a standard for our company and want to ask you to react again.
My statement is: "Go for a clean screen. Grey for inactive, green for active and red for alarm."
What do you think? Any idea, own experience, example or help is welcome.
Thanx,
Xander
