Wallpaper - Stay Happy Cool III

Our Stay Happy Cool III wallpaper by Mary Urban brings an expressive, hand-drawn floral composition to life against a deep blackboard-like charcoal background. The design features layered, mandala-inspired flower heads and delicate leaf vines rendered in a chalk or crayon-like visual texture. A vibrant palette of turquoise blue, muted purple, seafoam green, and soft chartreuse pops brightly against the dark backdrop, balanced by intricate white line work and cross-hatch shading. Produced as custom made-to-measure wall murals on PVC-free material with a subtle paper texture, this design offers a bold, artistic focal point that is easy to hang.

In the room

We see this wallpaper working particularly well in an entryway or a dining room where its graphic energy can set a welcoming, distinctive mood. In an entry or hallway, the dark ground adds instant depth, while the vibrant floral medallions create visual interest across smaller or fragmented wall sections. In a dining area, we would place this design across a main feature wall behind a sideboard or dining table, allowing the full scale of the floating blooms and swirling vines to remain visible and anchor the room.

Styling it

Because the pattern carries strong graphic contrast and playful color, we would keep surrounding elements relatively grounded to let the wall murals take center stage.

We suggest pairing this design with mid-toned or dark painted furniture that harmonizes with the charcoal background, or simple matte black metal accents that echo its fine contour lines. For upholstery or table linens, flat-woven textiles in solid turquoise or deep plum help carry the motif's colors into the room without introducing competing patterns.

Colour combinations

The wallpaper's palette centers around a textured charcoal black ground accented by chalky turquoise, lavender-purple, pale sage, and soft yellow-green alongside crisp white linework. When selecting paint for adjacent walls or trim, we recommend pulling out a soft off-white or light muted sage to keep the surrounding space bright and balanced. For a bolder, cohesive look, deep slate gray or muted teal on adjoining walls will envelop the space in rich color.
