Perhaps because it's the color of both the sky and the sea: In color therapy, blue tones are said to evoke clarity, pureness, and increased intuition. In the home, the shade is immediately calming and welcoming, whether used in a deep navy for a touch of drama, or a pale robin's egg in a more subtle space. Whatever shade of blue is for you—and whatever decorating style, from nautical to regal—ahead are more than 10 examples of blue-centered design that's just right.

ROYAL WALLS

A daybed in the guest room of this Hampton's home is draped with a vintage throw, and the sofa is by Mitchell Gold + Bob Williams; the cocktail tables from Tonic Home have custom-made tops by Plexi-Craft, the side tables are by Jonathan Adler, and the walls are painted in Benjamin Moore Regal in Patriot Blue.

BLUE IF BY SEA

In this Hamptons home decorated by Victoria Hagan, white furniture is part of a nautical theme that is just as striking as it is cozy. A white armchair and large white coffee table are cushioned by deep blue’s evocative of the nearby sea.

POP OF PASTEL

Fashion designer Lisa Perry stripped her family's Florida getaway to its purest white essence, then filled it with bright colors and bold artworks. The incredibly white living room sofa is by de Sede, the cocktail table is by Cini Boeri and the painting, Elaidyl Alcohol, is by Damien Hirst.

COORDINATED TONES

In the living room of a Paris apartment, which was designed by Jean-Louis Deniot, a sofa by Collection Pierre is upholstered in a Brochier fabric trimmed with ribbons by Samuel & Sons; lamps by Paul Evans flank a glass wall sculpture by Christophe Gaignon, the cocktail tables are custom designs, and the walls are painted in Paint Library's Eucalyptus.

CEILING, TOO

The tub in the master bath of this Paris apartment is by Jacob Delafon, with fittings by Waterworks, the sconces are by Niermann Weeks, and the Veere Grenney chair is covered in an Armani/Casa fabric; the chandelier is by Tony Duquette, and the vanity, mirror, and marble flooring are all custom designs.

UPHOLSTERED ACCENTS

In the living room of Patrick Printy and Dan Holland’s Arts and Crafts bungalow in Oakland, California, the custom sofa is covered in a linen by Peter Dunham Textiles, a pair of vintage John Stuart Clingman chairs is upholstered in a Ralph Lauren Home tartan, the bust on the custom cocktail table is by Oly and the rug is from Iran. The fireplace, repainted a high-gloss black, the bookcases and the oak flooring are all original to the house and the walls are painted in Benjamin Moore’s Smoke Embers.

ROOM TO ROOM BLUE

A foyer opens to a blue-tinted living room, which features crisp blue curtains, in this Oakland home. The walls are painted in White Dove and the ceiling in Stone Brown, both by Benjamin Moore.

RIGHT LIGHT BLUE

In this Manhattan townhouse, Quadrille fabric curtains with just a touch of blue play off the bold turquoise walls, painted in C2 Paint Luxe in Bewilder. The sofa and club chair, both by Anthony Lawrence-Belair, are covered in Holland & Sherry wools.

MOODY GREY BLUE

In the master suite of an Upper East Side home, the curtains in this monochromatic blue room perfectly match the decor. The armchairs are a 1950s Gianfranco Frattini design and the painting is by Friedrich Kunath.

SAPPHIRE BOARD ROOM

In an opulent boardroom, deep blue curtains and wallcoverings perk up a cognac table and chair set-up.
