Wallpaper - Happy Summer No4

Our Happy Summer No4 wallpaper, created by Treechild, brings together bold graphic shapes, lively curves and charming botanicals across a warm cream backdrop. A blue floral motif and a soft pink flower-like shape mingle alongside striped yellow and red arches, a warm orange shell form, playful yellow dots and a geometric red and green triangle. The painted-looking texture gives each flat illustration an approachable, expressive quality with a distinct postmodern influence. Made to measure on our PVC-free paper with a subtle surface structure, this design offers an uplifting balance of organic and geometric forms that feels both modern and genuinely cheerful.

In the room

We see this wallpaper working especially well where you want to introduce energy and personality without overpowering the room. In a playroom, nursery, or toddler room, the varied shapes and cheerful strawberry pink tones create an engaging, imaginative focal point. Because the composition mixes larger curved elements with smaller scattered accents, it holds visual interest across an entire feature wall behind a cot or bed, as well as along a wider play area.

In a living room, dining room, or home art studio, the design can serve as an eclectic accent wall. Giving the wallpaper a relatively uninterrupted wall allows the balance between the striped arches, botanical details, and graphic geometry to be appreciated in full.

Styling it

To let the graphic artwork take centre stage, we suggest pairing the wallpaper with simple, functional furniture and uncluttered surfaces. Painted furniture in soft off-white or muted cream keeps the overall look fresh and lets the playful shapes stand out clearly. If you prefer natural materials, light wood tones like birch or pale ash complement the warmth of the cream backdrop without competing with the vibrant strawberry pink, yellow, and blue elements.

For surrounding accessories and textiles, solid colours drawn from the motif, such as a plain soft blue cushion or an ochre throw, help tie the room together while keeping visual clutter to a minimum.

Colour combinations

The wallpaper palette combines a calming cream background with strawberry pink, warm orange, rich red, bright yellow, cobalt blue, and forest green.

When choosing paint for adjoining walls and woodwork, a warm off-white or gentle cream echoing the background provides a clean, cohesive border. If you want a more adventurous palette, pulling a muted terracotta, dusty pink, or soft cornflower blue onto surrounding trims or doors picks up on the secondary accents while letting the mural wallpapers remain the primary focus.
