Wallpaper - Stay Happy Cool III

Our Stay Happy Cool III wallpaper, created by Mary Urban, brings a playful and graphic energy to the wall through large, stylized floral mandalas and chalk-drawn botanicals. Set against a dark, textured chalkboard-style background, the expressive flowers feature layered petals, dot detailing, and delicate leaves rendered in vivid turquoise, soft blue, muted olive green, and rich berry purple. The hand-drawn crayon aesthetic gives the pattern an artistic and whimsical character, while the deep backdrop creates a striking contrast that lets each colorful bloom stand out. Our mural wallpapers are made-to-measure to fit your room dimensions and printed on PVC-free paper with a subtle surface texture.

In the room

We love how this design commands attention as an accent wall in an entryway or dining room. In an entry, the dark background and popping floral shapes create an inviting, creative first impression where visitors can appreciate the detailed linework up close. In a dining space, placing this wallpaper along a main dining wall grounds the room with artistic personality, especially when paired with a clear, uninterrupted wall area where the varying flower sizes and swirling vines can be seen in full.

Because the motifs have substantial visual weight and scale, we find the pattern performs best when it is not heavily covered by tall, bulky furniture. In rooms with bright natural light, the crisp chalk-like white linework and delicate petal textures stand out clearly against the deep black ground. Under warmer evening lighting, the berry and olive tones take on an intimate, cozy feel that makes a gathering space feel delightfully enveloping.

Styling it

The expressive, eclectic character of this wallpaper invites an interior approach that embraces playful color while keeping large furniture pieces grounded. We suggest pairing it with clean-lined mid-century or contemporary furniture shapes to provide a crisp counterpoint to the organic, hand-drawn motifs. Dark painted dining tables or natural walnut pieces echo the depth of the dark background, allowing the vibrant blossoms to remain the main event.

When selecting accents, echoing one or two of the floral shades through glazed ceramic vases, colorful dining chairs, or simple textured cushions helps tie the room together naturally. We recommend keeping surrounding rugs and large textiles relatively quiet and neutral so the energetic pattern on the wall remains the focal point without competing patterns on the floor.

Color combinations

The wallpaper itself combines a rich black chalkboard background with bright turquoise, cornflower blue, dusty olive green, soft lilac, and vivid berry purple, all outlined with textured white chalk lines.

To complement these shades, we suggest using off-black, charcoal, or deep slate on surrounding trim or cabinetry for a sophisticated, unified look. If you prefer a lighter, more open feel around the accent wall, soft off-whites and pale misty grays on adjacent walls provide a clean frame that lets the dark mural pop. For a more adventurous, color-forward space, pulling a muted olive or a dusty teal into surrounding painted surfaces creates a harmonious, designer-led palette.
