For generations, the marsh-surrounded town of Shimmer, Maryland has played host to a loose movement of African-American artists, all working in different media, but all utilizing the same haunting color. Landscape paintings, trompe l'oeil quilts, decorated dolls, mixed-media assemblages, and more, all featuring the same peculiar hue, a shifting pigment somewhere between purple and pink, the color of the saltmarsh orchid, a rare and indigenous flower. Graduate student Xavier Wentworth has been drawn to Shimmer, hoping to study the work of artists like quilter Hazel Whitby and landscape painter Shadrach Grayson in detail, having experienced something akin to an epiphany when viewing a Hazel Whitby tapestry as a child. Xavier will find that others, too, have been drawn to Shimmer, called by something more than art, something in the marsh itself, a mysterious, spectral hue.
