Colors can often be ambiguous, who it is that must be careful.
Most often, however, it is a danger signal to the observer – a wakeup call.
Something can be poisonous, cold, hot or many other things.
Especially in traffic, it may be necessary to change warning colors.
We humans turn to them and ignore the warnings due to habitual thinking.
While it is a safety in one way or another for the “flamboyant”.
Nature is different – there is rarely mercy, but cash settlement.
No color change but more “business as usual”
with different colored fly agarics, poisonous frogs or poisonous snakes.
The ambiguity consists in who it is that must be most careful.
Who should see and who should be seen.
