Google image search on on a mobile phone shows placeholders in the split second before the images are loaded. The placeholder tiles’ colors are based on the color range of the image being loaded.
Google Image Essence: Malewich, Klein, Rothko is a permanent visualization of this ephemeral image loader. The Diasec prints show screenshots of Google color range placeholders of search results for different artists, whose work is strongly color based e.g. “mark rothko oeuvre”.
