Why are the houses in many communities in Newfoundland painted in varying colours ?
There’s no one reason for this, however it makes sense to have houses in coastal communities painted in varying colours so that fishermen at sea can more easily find their way home. The mass effect of a group of different colours at a distance, against a background of green in summer and white in winter, acts as a navigational aid. Otherwise, the choice of colours is often a personal statement of individuality.
