Kerry Washington's unorthodox bed sheet color is proven to promote relaxation – experts say it's (surprisingly) one of the best shades for sleep

When considering our bedroom's design, we are challenged by two imperatives: an interest in making the space beautiful and the need to be sure it is a calming sanctuary. These goals needn't be mutually exclusive. By using simple methods like calming bedding color and inviting lighting, we can create spaces that are simultaneously relaxing and stunning enough to spark joy.

Kerry Washington leads a masterclass in this principle with her gray bedding. We spotted the actress's light grey duvet and pillow covers in an Instagram post where she is meditating on her bed. Meditation seems like an intuitive action, given that experts say gray is the best bed sheet color to promote sleep. Of course, it's best when paired with cozy sleepwear; we love Washington's gray silk robe Casablanca Robe from Olivia von Halle (available at Net-a-Porter).

Carlin van Noppen, interior designer and owner of Fig Linens and Home with over 20 years of experience in the bedding industry, explains: 'Cool toned bed sheets are the best kept secret for better sleep. Though people tend to consider white to be the ultimate neutral in a bedroom, they are missing out on the calming properties of gray, blue, and green bedding. The natural origins of these shades have a relaxing effect on the brain that makes one feel like they are drifting off in a tranquil outdoor environment.'

Editor's Picks for Gray Bedding

How do you style gray bedding in a relaxing bedroom? There are several schools of thought. Carlin shares: 'The simplest way is to go for an all gray look, like we see in Kerry Washington's space. However, using gray bedding doesn't have to mean a minimalist bedroom. Gray looks wonderful paired with blue or white for a contrast that stays in the same relaxing family. You can also try integrating patterns with gray bedding that features florals, or geometric shapes.'

She continues, 'When styling this look, be sure to integrate lots of texture to create a space with visual interest. For instance, a gray faux fur throw, linen pillows, or a silk sheet set can help make a gray design much more interesting.'

Choosing bedding is about design, but it's also about how you feel in your bedroom. Gray is one of the best choices to promote a relaxing atmosphere – just ask Kerry Washington.
