1. Don’t match your neighbors.
2. Big House? Paint it a medium-dark color
3. Little House? Light-medium color.
4. Whichever color you pick , remember it will look 25% lighter when painted on an exterior.
5. Don’t paint your trim to match your white vinyl windows. Pick a warmer white ( with a touch of yellow) , no one will ever notice.
