<human>:  Was it typical to see Johnny Cash on stage in a rainbow-colored outfit?
<bot>: No, Johnny Cash was not known for wearing rainbow-colored outfits. Johnny Cash regularly performed dressed all in black, wearing a long, black, knee-length coat. A rainbow-colored outfit would consist of the colors red, orange, yellow, green, blue, indigo, and violet, so Johnny Cash was not known for wearing rainbow-colored outfits. He was known for wearing all black, though.
