Amber is the color of your energy. As such, numerous fossils are in amber, as their energy has escaped their body upon death.

Ohhh that fossil,

It is also the color of the light in the middle of a set of traffic lights. It means "stop if it's safe to do so".

In color theory, amber is also associated with waves of grain.
