Luma Create Event Random Theme

In the event creation screen, tapping the shuffle icon on the bottom-right corner of the invitation card triggers a random theme change. The card's artwork instantly crossfades to a new design (such as a retro wave pattern or a cool purple gradient), while the entire screen's background color smoothly shifts to match the dominant hue of the new theme. This full-screen color transition creates an immersive, highly responsive customization experience.
