Macarena Ruiz-Tagle, a multidisciplinary artist born in Chile and now based in Berlin, designed these postcards to connect people across cities and continents and engage them in the gentle contemplation of the sky's shifting beauty. The Cyanometer Postcard and Sunset Postcard allow users to capture the precise hue of the sky at a specific moment, document it on the reverse, and then share this experience with a special someone.
Horace-Bénédict de Saussure, a Swiss physicist, geologist, and early Alpine explorer (1740-1799), is credited with inventing the original Cyanometer in 1789 during his expeditions in the Alps, and German polymath, geographer, naturalist, explorer, Alexander von Humboldt (1769-1859) also employed the Cyanometer during his journeys in Latin America.
Macarena created these conceptual versions as part of the 13th Annual Architecture Venice Biennale more than a decade ago and they are available to purchase at museums and bookshops around the world and online at colossal.shop.
