I love when retail spaces and art installations mingle together. The Run Colors trainer store in Poznań, Poland features seven rainbow rope colours, inspired by shoelaces and brand lines. Designed by Mode:lina Architekci, the ropes were placed in prismatic shapes to refer to the fast movement of a runner as colour bounces across walls and onto carpets. I particularly love the charcoal walls and antiques. While white will always have that gallery appeal in a retail space, charcoal is one of my favourite ways colour can be highlighted (particularly when products have lovely white details like trainers do)…
