We spend so much time making tiny decisions about seemingly tiny things. From the clothes we wear to the homeware we buy, we spend more of our lives choosing colours than you might expect. Even if you were to go shopping for something as simple as a toothbrush, you’d find yourself confronted by a rainbow of different options. And whether it’s intentional or not, you eventually have to make that choice.

How often do you think about how colour impacts your life? Do you really care about whether your toothbrush is blue or green? I can’t say I’ve considered it much either. In fact, it wasn’t something I’d really thought about until I saw a video on my TikTok For You page (where else?) about the concept of ‘pink and purple sisters’.

Suddenly, I was taken back to my childhood bedroom, where the walls were coated in a thick coat of pink paint with a ballerina and princess frieze running around the perimeter. Make the short journey across the hallway to my sister’s room, however, and you’d come across an entirely different scene: the walls covered in a light purple paint and a floral purple duvet. We were, it seems, the definition of ‘pink and purple sisters’.
