Architecture, Building and Structure Design Neumatt Sports Center by Evolution Design Neumatt is not one of the many standard sports centers in Switzerland. Inside, it is a true color burst of green, yellow, red and blue. These rainbow-like colors not only help children to navigate around, but it’s also more playful and taps into the way children see the world. By designing a bright sports hall flooded with daylight, the architects wanted to encourage people to spend more time doing sports and truly enjoy being there. Outside, the facade has been designed to blend in, with an upper glazed level that reflects the sky and changes the color depending on the time of day.
