Can you really walk through a rainbow? Yes, in Aarhus, Denmark, on top of the roof of the Danish Art Museum ARoS, to be precise, where renowned artist Olafur Eliasson has implemented a spectacular installation: a 150-meter circular walkway titled “Your rainbow panorama”. Visitors to the rainbow ring located at a height of 50 meters can enjoy a breath-taking 360° view of the harbour town. The daylight filtering through the curved glass walls in all colours of the spectrum, each of them specifically made for this purpose, creates the impression of being inside a rainbow. For the installation to be visible also at night, Eliasson relied on Zumtobel, his long-term partner in lighting: from dusk till dawn, a specially developed lighting solution incorporating 116 recessed uplights installed along the inner periphery of the ring transforms the white ceiling into a source of light, so that the panoramic walkway appears like a rainbow hovering above the museum.
