Yes, this topic is drifting, but there is something that has been missed.
Seems like you want orange, but you dont define what constitutes 'unstable'. I would think you are referring to packet loss, or flapping. Therefore, look at the ping probe parameters and adjust them down to be almost impossible to be considered up. There are retry and time parameters. If you said, if the latency is over 1ms, and only try once, that might make it change color. If possible, load the link to force the condition to test it. I am sure if it goes red, that will draw your attention, and if it isnt really down, and just sustaining packet loss, you needed to look at it anyway. If its down, you needed to be there anyway. You will eventually obtain your optimum threshold for your 'unstable orange' condition. Seems you want a tri-state device condition. Up/packet-loss/down. If there are only two states, this will still work because it will require your attention in either an unstable or down condition.
You could also have an alternate ping probe with a different name, but is much more sensitive. I tried to force this on my network, but the ping times are too low. But I observed another helpful indicator in testing. If you are using links with bandwidth indicated, at a certain threshold, they change color to indicate at least 'heavy traffic'. That is very handy on backhaul links. Heavy traffic conditions could cause 'instability'. If its an RF condition causing instability, thats a whole new topic.
Hope this helps...
