Here is a nice Storypeople story called "Purple Madonna:"
One time on Hollywood Boulevard I saw a young girl with a baby. It was a crisp winter morning & her hair shone dark purple in the sun. She was panhandling outside the Holiday Inn & the door clerk came out & told her to be on her way & I wondered if anyone would recognize the Christ child if they happened to meet. I remember thinking it's not like there are any published pictures & purple seemed like a good color for a Madonna so I gave her a dollar just in case.
