Pilgrims in Zurich

Shades of Red; Where are the pillars?
At the end of the rainbow, where the indigo turns to red.
Shades of Grey, Where is the moonlight?
Hidden, shrouded by the clouds which drives out the rain.
Shades of Silver coloured petals, Where are the flowers?
Trampled, Under our feet.
Shades of Black, dotted with white, Where are we?
Far, far away; from the book of life.
