Wallpaper - Happy Summer No4

Our Happy Summer No4 wallpaper by Treechild brings together a lively collection of graphic, abstract shapes against a warm cream ground. We have combined stylized blue floral silhouettes, strawberry pink organic forms, and yellow and red striped arches with playful accents like an orange shell motif, scattered yellow dots, and a graphic red and green triangle. The painted aesthetic and bold flat forms give the design a cheerful, whimsical character with a distinctive postmodern feel. Produced made-to-measure on PVC-free paper with a subtle surface structure, this design is simple to hang and creates an expressive focal point in any interior.

In the room

Because of the varied motifs and energetic composition, we see this working particularly well as an accent wall in a living room, dining room, or bedroom where the full arrangement has room to breathe. The contrasting geometric and organic shapes draw the eye across the surface, making it an engaging choice behind a low sofa, a dining table, or a bedhead. In a playroom, nursery, or creative home office, the bright rhythm of shapes adds personality without needing additional wall art. For rooms with generous natural daylight, the strawberry pink tones and vivid primary accents stay crisp and distinct against the neutral cream background.

Styling it

When styling around this mural wallpaper, we suggest letting the graphic artwork take centre stage by pairing it with simple, confident furniture silhouettes. Mid-century modern or contemporary eclectic pieces with clean lines balance the busy rhythm of the motifs nicely.

To keep the room grounded, we like incorporating light or natural wood tones, such as birch or light oak, alongside smooth painted surfaces. You can also pick up on the joyful aesthetic by introducing small decorative ceramics or lighting in solid primary accents that echo the cobalt blue, warm orange, or soft pink in the print, keeping larger upholstery relatively neutral.

Colour combinations

The design itself features a rich mix of strawberry pink, cobalt blue, warm orange, sunny yellow, vibrant red, and deep green, all anchored by a warm cream backdrop.

For surrounding walls and woodwork, a soft off-white or light cream that matches the background tone creates a seamless and open feeling. If you prefer more contrast, a muted sage green or a dusty rose on adjacent surfaces pulls directly from the artwork while maintaining a cohesive palette. For accent elements, rich terracotta or warm ochre complements the bolder tones in the wallpaper without overwhelming the space.
