Color of the month: Optimum Blue

Perfect weather is plentiful in July, showing off in the forms of deep blue skies, soft breezes and idyllic temperatures. It’s a month of beckoning beaches, pool decks and patio umbrellas, each calling us outdoors for every available moment. The soothing deep blue of Behr’s Optimum Blue M540-7 perfectly captures the essence of a clear July sky, which is why we’ve selected it as the Color of the Month.

Optimum Blue is an excellent choice for a chance of pace on a home’s exterior. This well-balanced shade offers just the right amount of cheerful intensity for house paint, especially when adorned with classic white trim. It also stands out well against stone and brick elements in gray and beige tones.

A bold, beautiful entryway is a welcoming entryway. Optimum blue, on the top half of the walls of a foyer or entry room, creates a stunning yet relaxing seaside vibe when paired with white on the bottom half of the walls. Wood floors and furniture add to the natural outdoorsy energy of the space. Sand-hued items such as a wicker basket and collectibles in tan and gold complete the seaside atmosphere.

Optimum Blue is also an excellent accent color in a room with white walls. Paint a stylish chevron-themed design in blue to add a focal area to an otherwise blank space. Pair the artistic detailing with a deep blue armchair and several woven-fiber elements for a chic, refreshing look.

Boost the bedroom’s ability to relax the mind by adding Optimum Blue to one or all of the walls. A focal area in blue, adorned with stamped white anchors, adds a nautical look between white and gray striped walls. The remaining walls, in white or gray, keep the theme subtle yet purposeful and inviting.

Optimum Blue coating all the walls adds a modern yet classic look to a bedroom using those same gray and white accents. It’s the perfect color to balance out a space that has a wall-sized window or sliding door that lets in lots of light.

The aptly named Optimum Blue is an optimal color for a bathroom, too. Create a modern yet peaceful look by painting the walls in this hue, accompanied by cabinets in a soft gray. This look pairs well with wood floors and white and gray tiles or bricks.

      Hello Thao, Thank you for visiting our blog!
      Dark color trim is a great option with gray siding.
      Here are some great combinations.
      Superior Blue S490-7/Cosmic Quest N460-4
      Infinite Deep Sea S500-7/Slate Rock N460-5
      Dark Denim S510-7/Letter Gray PPU24-20
      Hope this helps!
      Colorfully Yours,
