I’ve done this a few times, where I take a picture of a rug (usually), and build a palette using its colors. Sometimes I make something with that palette, but not always. This rug is from the Iowa Old Capitol in Iowa City, Iowa. The University of Iowa campus is built around the building, which was the capital of Iowa from 1846-1857. If I remember right, this reproduction rug was made based on an original rug (although I don’t know from what time period). If you are in Iowa City, this is worth a tour — the reverse spiral staircase is beautiful.
