If you like the current color of a wall, trim or accent, use it as a starting point and pick complementary colors
If you have a distinct style of home, research traditional color schemes. They can provide time-tested ideas for colors that work well.
Because colors may appear different depending on the time of day, paint a section of the house where wall, trim and accent colors can be viewed together. Then check them throughout the day to see how they look.
To highlight architectural details, such as shutters and columns, choose a color that contrasts with the wall of the house. For example, if the wall of your house is a light color, choose a darker color.
You can minimize attention to unattractive elements, such as downspouts, air conditioning units, vents and gutters, by painting them the same color as the wall of the house or by choosing a trim color that is a similar shade.
