 He began to use fluorescent Day-Glo paint, which has an uncanny glow that recalls the artificial lights of postmodern society and the bright government-issued signs that mark streets and workers' clothing.Halley also uses Day-Glo colors in response to developments in modernist painting—a "hyperrealization" of art-historical motifs, in Halley terms (following Jean Baudrillard)—and as a means of delineating space on his canvases.Halley also began to employ Roll-a-Tex, a textural additive that gives his "cells" and "prisons" a tactile, architectural quality, as Roll-a-Tex is most often used as surfacing in buildings such as suburban homes and motels.
