国立アメリカ歴史博物館さんのインスタグラム写真 - (国立アメリカ歴史博物館Instagram)「Looking for a distraction on a Sunday afternoon? (Or inspiration for a last-minute Valentine's Day card?) We recommend swiping through this sample book of colored thread, created by Valentin Emmerling in the 1840s. Emmerling was a professional fabric dyer—someone who mixed colors and then dyed fabrics and threads for textiles. This sample book was one of the ways he showed potential clients the range of options available to them for coloring their fabric. For scale: the book above is over 10 feet long and includes more than 1,000 individually numbered samples, all categorized by the hue on the color spectrum. Follow the link in our bio to learn how Emmerling produced such vivid colors in the 1800s: http://s.si.edu/RichReds #History #AmericanHistory #TextileHistory #BusinessHistory #ValentinesDay」2月15日 4時38分
