Confusion about amber

So I'm coming to a few decision-points in my life.

As I don't seem to be able to make a decision, I've made a necklace instead - mainly upcycled from that haul of assorted costume jewellery that my marathon-runner friend gave me a while back. The theme is amber. It is quite a heavy necklace because the blue glass pearls and the amber glass focal are both pretty heavy, and there's a fair amount of metal in there too. The disc-shaped spacers are dark-brown wood, although in this picture they look almost black in the sunlight. They go well with the amber.

But what does amber mean, really?

Amber with red means: wait, but get ready to go.
Amber after green means: go, but get ready to stop.


Argh! It's too confusing! Am I coming or going?
