Here's an analogy. Anyone who has spent time on a firing range will have seen simple colours used to signify danger and safety. Funnily enough red and green.
Red flags flying and red lights on means DANGER bullets flying all over the place keep yer head down!
Green lights on means ALL CLEAR safe to bimble about, chilling and smoking tabs etc.
Red is the international symbol for danger, caution and alertness.
Green is the international symbol for safe and clear.
Sorry guys but this is an own goal in my book.
