silver

I love how the colour green can be both positive (green growing things, etc) and bad (jealousy etc)

Yes, also "green" as in "young" to highlight the memory/nostalgia.

I see, as I linger the land of my birth,
I am welcomed in the language I cherish.
I will receive there hospitality and love, when I reach it,
That I'd trade not for tons of gold.
