Temp Guage colours

Would it be difficult to add in a feature that can for example turn a temp sensor red if over a certain temp??

Thanks in advance

No, I don think that it would be difficult. I guess that the approach would be similar as the icon changes for the binary sensors. The issue is that we are already using different color for different badges. Sensor are red, scenes are green, script are gray, etc.

How about the fill colour? Could use a 20% of relevant colour so it do t look too out there??
