In a bedroom I recommend painting the lively hue on the headboard wall — either the entire wall or just a part of it — to anchor the bed and create a focal point.
The dining space shown here features a pretty berry-hued shade on the large window flanking the fireplace. This is a clever way to bring color into a space, because you can roll the shade up and away whenever you want to strike a more neutral tone.
And by installing artwork closer to the ceiling than the ground, as in the living room here, you draw the eye up, giving the feeling of an open and airy space.
The dining room above has a deep, elegant color palette that gets a terrific boost of energy via the zesty orange rug. The bedroom at left has a cool and relaxing vibe, with just the right amount of perky blues thrown into the mix via the rug.
