There's a moment, usually after noticing a freshly painted house on your street, when the thought strikes: it might be time to do something about ours. Choosing exterior colours is one of the most visible decisions a homeowner can make — and one of the most permanent. Get it right, and your home looks more confident, more cared for, and more in tune with the street it sits on. Get it wrong, and you'll be living with the results for years.
