A retroreflective article (30, 50) has opaque pigment particles (38, 58) dispersed in a retroreflective region (33, 53) of a front portion (35, 55) of a sheeting (32, 52) that includes a body portion (34, 54) and a multitude of cube-corner elements (36, 56). The opaque pigment particles (38, 58) scatter white, yellow, or light brown light to allow the retroreflective article to demonstrate improved lightness and, if colored fluorescent, improved fluorescence. The improvement in lightness and fluorescence makes the retroreflective articles more conspicuous to persons during the daytime.
