Brunette Girl Undresses Her White Top And Blue Jeans At The Window

Dyeing
Traditionally, jeans are dyed to a blue color using indigo dye. Some colors that can be achieved however are pink, blue, yellow, black, and white. These colors are achieved by coloring other fabrics to resemble jeans. Approximately 20 million tons indigo are produced annually for this purpose, though only a few grams the dye are required for each pair these trousers.
