Choosing an Oceanic Color Palette
To mimic the ocean, it’s best to choose soft blues and greens as the primary colors in the nursery. And the great news is that these colors are so calming which makes them perfect for a nursery.
You can then add pops of vibrant coral, yellow, and purple to add some fun to the space. To maintain balance, consider incorporating neutral tones like sand and driftwood, which complement the oceanic color palette. You can always grab a few paint samples from Sampilize to test out your options.
Wall Decor that Makes a Splash
Set the underwater scene with a mural or wallpaper depicting ocean scenes. This can create a beautiful focal point in the room.
Additionally, decals of sea creatures, shells, and coral can be strategically placed to emphasize the underwater theme. If you prefer a more refined touch, framed ocean-themed artwork or photographs can add a touch of elegance. For those feeling crafty, DIY projects like driftwood wall hangings can add a unique and natural element to the decor.

Furniture That Emphasizes Fluidity
Selecting furniture that reflects the fluidity of the ocean is definitely worth considering. Choose a crib with curved lines reminiscent of waves to create a soothing and dreamy atmosphere. Complementing the crib, a rocking chair or glider in a nautical style can provide a cozy nook for nursing or cuddling.
To further emphasize the under the sea theme, add a dresser or changing table with rope or shell accents.
Completing the look, a bookshelf shaped like a boat or lighthouse can be a really fun element to include in the space.
