PROBLEM TO BE SOLVED: To provide a ceramic color composition which does not contain lead and bismuth, gives a glass plate with little decrease in strength, and is excellent in acid resistance and mold release characteristics. SOLUTION: The ceramic color composition is comprised of 60-90% glass powder, 10-40% inorganic pigment powder, and the like by mass. The glass powder consists, by mol%, of 35-55% SiO<SB>2</SB>, 5-35% ZnO, 2-18% B<SB>2</SB>O<SB>3</SB>, 7-18% TiO<SB>2</SB>, 1-30% Li<SB>2</SB>O, 0-30% Na<SB>2</SB>O, 0-8% Al<SB>2</SB>O<SB>3</SB>, 0-8% ZrO<SB>2</SB>+SnO<SB>2</SB>+CeO<SB>2</SB>, 0-5% La<SB>2</SB>O<SB>3</SB>, 0-5% P<SB>2</SB>O<SB>3</SB>and 0-8% F+Cl. MgO+CaO+SrO+BaO is 8% or less. COPYRIGHT: (C)2004,JPO
