Here is the extract from a poem "Aunt Jennifer's tigers" by Adrienne Rich-
Aunt Jennifer's tigers prance across a screen
bright topaz denizens of a world of green.
They do not fear the men beneath the tree.
In the above extract what does the sentence- "bright topaz denizens of a world of green" mean,
I did not find any relation between the words 'topaz' and 'denizens'.
