Petrol - the greyest romance

"Your challenge, should you choose to except it, is to write a paragraph - may it be dialogue, a description, part of a solilioqy or a diary - inspired by a specific colour chosen by the person who writes the previous chapter, e.g. I write a paragraph and choose the colour 'red', then the person after me writes a paragraph inspired by the colour red. Not as easy as it sounds, but give it a go!"
