The colour hunt is really just a reason to leave the house. To take the long way back, to walk the street you cross every day with your eyes up, to stand still for a moment in front of something you have passed a hundred times without ever once looking at it.

Almost always, the shade turns up somewhere ordinary — a chipped bollard, a neighbour's door, the fruit already sitting on your counter. That is the whole idea. The score is only the excuse; what you keep is the ten minutes you spent paying attention.
