A glass that includes Pr.sub.2O.sub.3 and Nd.sub.2O.sub.3 such that the sum of Pr.sub.2O.sub.3 and Nd.sub.2O.sub.3 is greater than 0.2 mole % and the ratio of Nd.sub.2O.sub.3 to Pr.sub.2O.sub.3 is greater than 0.5 and less than 3. Further, the sum of any chromophores in the glass from the group V.sub.2O.sub.5, Cr.sub.2O.sub.3, MnO, Mn.sub.2O.sub.3, Fe.sub.2O.sub.3, CoO, Co.sub.3O.sub.4, CuO, NiO, Nb.sub.2O.sub.5, CeO.sub.2, Ho.sub.2O.sub.3 and Er.sub.2O.sub.3 is less than 0.1 mole %. The glass can be characterized by a substantially pink color upon exposure to an incandescent light source and a substantially green color upon exposure to a fluorescent light source. The glass can optionally include one or more fluorescent ions selected from oxides of Cu, Sn, Mn, Ag, Sb, Ce, Sm, Eu, Tb, Dy, Tm, and combinations thereof, such that a total concentration of fluorescent ions is from greater than or equal to about 0.01 mole % to less than or equal to about 5.0 mole %.

Multicolored glass-based articles and methods of manufacture are disclosed. The method includes forming a glass-based part and exposing a first region to radiation and a second region to radiation such that the first and second regions have different sized metallic nanoparticles, resulting in a multicolored glass article.
