In the early twentieth century, the phrase, "color fast fabrics" was used extensively in marketing clothing and fabric.
During the early part of the twentieth century, a movement was started to really insure that fabrics would remain color fast. During World War I, European dyes were not available due to blockades. The American Association of Textile Chemists and Colorists was formed in 1921 and is still in existence today. Their website is fascinating and has a great textile timeline here.
Color-fast fabrics are an interesting topic. Originally the thought was to inhibit fading of fabrics and a lot of work was done by a UK manufacturer, James Morton. He literally tested fabrics not only at home but sent fabric swatches to his brother in India to see how they would withstand extreme sunlight. With the assistance of a chemist named John Christie, he developed "sundour" fabrics that could withstand sunlight. A great website is here that explains some of his work.
By the 1920s, most ads promoted that fabrics were "color fast":
