From Fox News

“When excreted in the urine, indoxyl sulfate can be broken down by bacterial enzymes to form indigo and indirubin, which are blue and red, respectively, creating the color purple when combined,” the doctors explained in the case study, noting other bacteria such as Pseudomonas aeruginosa, Providencia stuartii, and Escherichia coli can also produce a similar effect.
