The present invention provides a ceramic color composition which comprises, as a solid powder, 50 to 90 wt. % of a mixture containing 5 to 95 parts by weight of a first lead-free glass powder comprising at least SiO2, ZnO, and B2O3 as glass components, and 5 to 95 parts by weight of a second lead-free glass powder comprising at least SiO2, Bi2O3, and B2O3 as glass components, 10 to 40 wt. % of an inorganic pigment, and 0 to 10 wt. %0 of an inorganic filler. The composition is free of lead and exhibits an excellent mold release property during the heat-molding process of a glass plate having the composition printed thereon. After firing, the composition is excellent in acid resistance, coloration in the bus bar portion, and plating resistance.
