The 33-year-old singer and "American Idol" judge debuted new purple hair in a photo Thursday after kicking off the European leg of her Witness tour.
The picture shows Perry with her bright new hair and complementing shades of pink and purple makeup. She jokingly compared herself to a Teletubby in the caption.
"Call me the purple teletubby ok," the star wrote, adding a purple heart emoji.
Perry performed Wednesday in Cologne, Germany, and Thursday in Antwerp, Belgium.
She will visit several other European cities before performing in Africa, Australia and New Zealand during the summer.
"I think sometimes there's a need for a physical transformation when you've gone through such an emotional and spiritual transformation," the star told Entertainment Weekly in June 2017 after getting a pixie cut.
"Someone asked me the other day, 'What's the biggest thing that changed about you when you cut your hair?' I said, 'I started doing my hair hair and makeup for myself,'" she said.
