Blue is the colour of your smile as you lie in your grave,
Colours robbed from you with the air you breathed.
I wonder about the shade of your softly closed eyes
And that of the world they held in their throes:
The golden fire they once flashed about, faded to ashes
Life, a melancholy tone of greys and blues.
