Studies show that homes with blue kitchens, often in soft grey-blue, sold for a premium. In this kitchen, designed by Kelly Gammie of Eucalyptus Design, the walls are painted in Resene Half Duck Egg Blue, a popular grey-blue for the home. The cabinetry is painted in Resene Half Delta to complement walls and balance the Resene Delta doors throughout the rest of the house.

Homes with light pale blue to soft periwinkle blue bathrooms sold for way more than expected. This bathroom is a stunner, painted in the dreamy blue-grey of Resene Hermitage, with a Resene Quarter Carrara board and batten feature wall behind the freestanding bathtub. It features in this beautiful replica villa home, built by David Wraight Villas.

Homes with light beige or pale taupe living room walls sell for more than expected. Take your cue from Claire and Mark Bramwell's home, where the main living area is painted in Resene Quarter Napa.

It also found that homes with slate blue to pale grey blue dining rooms also sold for more money. The lounge, breakfast nook and living room of this bed and breakfast are painted in soothing Resene Periglacial Blue. The trims are Resene Blanc and the ceiling is Resene Half Merino. For more about Arthouse Bed & Breakfast, see www.arthousebnb.co.nz.

A home's exterior colour may also have an impact on its sale price. Homes painted in greige, a mix of light grey and beige, sold more than similar homes painted in a medium brown or with tan stucco.

Not a week goes by when someone doesn’t knock on the door and asks for the exterior colour of this house, built by Marcus Grayling of Grayling Builders, and designed by LAD Architecture. The weatherboard is painted in Resene Half Napa, and the roof is painted in Resene Grey Friars.
