Lawsone and Citric Acid

Hello. for my chemistry experiment, I am using a colorimeter to measure changes in color intensity when adding citric acid to henna (the chemical dye is called lawsone). I am not sure what products are created when this reaction happens. Can someone please help me?

Acid washed jeans are faded because the acid reacts with the specific dye in the fabric. The reaction alters its "conformation" (lack of a better word), and causes it to lose its color property.

 

hope this helps.
