Write a rainbow

Write a short story where the first sentence includes the word "red."  The first sentence of all the subsequent paragraphs have to include a new colour.  You are only allowed to use the colour word once in each paragraph, but must suggest it in as many ways as possible.  E.g.

The world had turned grey. Nothing but mud and asphalt surrounded the unpainted house, little more than a box made of concrete blocks. Charlie, dressed in faded work pants, rubber boots, and a thick wool sweater, steadied himself with a hand on the top rail of a weathered cedar fence. Behind him, nothing but ash-coloured sky, bare trees, and plumes of smoke belching from the factory in the distance. A lone sparrow rested on a branch, one beady eye watching.
