A fluorescent red-orange retroreflective article includes a polymeric matrix and at least one fluorescent dye added in an amount that provides the article with a red-orange color under daytime lighting conditions. The article also includes cube corner elements disposed at a back side of the polymeric matrix. The article can exhibit a retroreflectivity of at least 350 or 500 cd/(lux·m2), and a brightness Y of at least 20, 30, or 35. The article can exhibit a color within a preferred red-orange color space bounded by CIE chromaticity coordinates (0.560, 0.380), (0.580, 0.355), (0.633, 0.366) and (0.610, 0.390).
