the hidden fourth colour

Look beyond the charming 1990s throwback aesthetic of this Memphis Mayhem wallpaper by Graham & Brown, past the striking red, yellow and blue stripes, and you might spot a fourth colour – green. The brand is so committed to sustainable initiatives that it will be totally carbon neutral from January and, while preparing for this milestone, it has been planting three trees for every one it pulls down. So far this century, it has planted 16.5 million indigenous saplings, creating wildlife habitats and sustaining forestry, with a further 25,000 planned for this winter. All of which means that by buying into the brand’s collection you can rest assured that your decorative choices are supporting the environment, too.
