 So what colour is this playground going to be? It's going to have a mixture of purple and yellow and orange and green, which sounds like a lot, but honestly there's a lot of grey in Finland. A blast of colours in the cold Helsinki winter will cheer people up. Oh, and we wanted it to be something else than primary colours, because a lot of the times children's playgrounds come in red and yellow and blue, and we wanted it to be a little bit different from that.
