Blue jeans are a classic symbol of American fashion, but did you ever wonder how your blue jeans got their color?
Synthetic indigo dyes are used to give jeans their hue, but that was not always the case. Only two countries, China and Germany, currently manufacture the dyes that are used to color jeans, with China producing 90 percent.
Synthetic indigo is derived from coal tar and toxic chemicals that are fused together under conditions so extreme that making it in the United States is cost prohibitive, due to strict environmental and safety regulations.
