The Lancaster County Amish quilt tradition channels the entire decorative impulse of a plain people into saturated solid-color blocks — ecclesiastical violet, deep forest green, vermilion red — framed by wide ink-black borders. No figurative ornament, no gradient, no pattern within color: just large geometric fields that anticipate Rothko and Newman by half a century. This system translates that bold color-field geometry into interface design: sharp-cornered panels, flat black framing, and a centered symmetric composition that echoes the Diamond in the Square.
