Blacklight mini-golf is the aesthetic of the blackout indoor course: a fully darkened room where hand-painted day-glo monsters and paint splatters cover black walls, lit only by ultraviolet light so the fluorescent pigment seems to glow from within. It is North American family-entertainment kitsch — brushy, comic, and unapologetically loud.

This design system translates that venue into pixels: a black-painted ground, UV-fluorescent green as the hero glow, and a riot of hot pink, acid lime, electric cyan, and glow orange. Type is hand-lettered and cartoonish; every bright mark wears a blacklight halo.
