Abstract
A retroreflective material providing a visual coloration includes a body member with microprisms on its rear surface. Some of the microprisms have a retroreflective interface and the remainder have a colored non-reflective coating thereon. As a result, light rays entering the front face which impinge upon the prisms with the retroreflective interface are redirected so that they exit the material in a parallel path. Light rays which travel to the color coated prisms are refracted from those prisms and impart a visual coloration to the material in daylight and ambient light.
