In order to promote Rainbow, Carey embarked of her fourth headlining and third worldwide tour. Titled the Rainbow World Tour, it included nineteen shows: six in Europe, four in Asia, eight in the United States, and one in Canada. For Carey's previous two tours, she had only visited Europe and Asia, due to the mixed reception of her debut stateside tour in 1993. However, after achieving record-breaking ticket sales throughout Asia and instant sellouts in Europe, Carey felt secure enough to once again tour her native country. The set list featured songs from most of Carey's previous studio albums, as well as some tracks from Rainbow. Missy Elliott and Da Brat served as opening acts for the US leg of the tour. Ticket sales were very strong; the entire US leg sold out in a matter of days. The Asian and European leg mirrored the commercial success of her previous two tours. Reviews for the tour varied from positive to mixed. Some critics and fans reproached her of having a "tired and hoarse voice," while others commented on Carey's choice of wardrobe. Several critics and many concert-goers praised the tour, calling it an intense celebration of Carey's career.
