Wallpaper - Stay Happy Cool III

Stay Happy Cool III by Mary Urban brings an expressive, playful energy to the wall with large, chalk-drawn abstract florals set against a deep blackboard-like dark background. Stylised mandala rosettes and botanical blooms in cool tones of teal, cornflower blue, purple, soft mauve, pale sage, and crisp white textured lines pop with clear graphic distinction. Our made-to-measure wallpaper is printed on PVC-free paper with a subtle surface structure, creating an artistic statement wall that feels both hand-crafted and contemporary.

In the room

The high-contrast palette and bold scale make this design especially effective as a feature wall in a dining room or entryway. In an entry or hallway, the dark ground gives the space an immediate sense of intimacy, while the chalky floral bursts bring light and visual rhythm as soon as you step inside. For a dining area, we like placing this design along a main wall where the detailed floral rosettes remain largely unobstructed above table height, allowing the full composition to anchor the dining setting.

Styling it

Because the floral illustration has a strong graphic character and intricate chalk-like line work, we suggest keeping adjacent furnishings relatively grounded. Clean-lined contemporary furniture or mid-century shapes in warm wood or painted finishes balance the cooler tones of the pattern without competing for attention. Simple textiles in natural weaves and modest accents let the floral composition remain the focal point of the interior.

Colour combinations

The wallpaper features a dark, chalkboard charcoal base layered with cool teal, sea green, lavender, purple, muted yellow-green, and chalk white. When painting adjacent walls or selecting woodwork, we recommend picking out a muted chalky off-white or a soft, desaturated sage to mirror the lighter details in the petals. If you prefer a moodier, enveloping scheme, pairing the surrounding trim or walls with an understated deep slate grey or softened charcoal creates a seamless, cohesive backdrop.
