The only reason you're asking this question is because your chemistry instructor has posed it to you. Think about what happened in lab: You synthesized the indigo, but it wouldn't dissolve in water to dye your cloth sample. So, you reduced it with sodium dithionite, whereupon it turned to a yellowish-green color. Then, you dyed your fabric, and let it dry. What happened when it dried? What makes your blue jeans blue?
