A blue-green colored glass composition includes a base portion, such as a
conventional soda-lime-silica base, and major colorants. In one
embodiment, the major colorants include 0.7 to 0.9 weight percent total
iron (Fe.sub.2 O.sub.3), 0.2 to 0.3 weight percent FeO, and 0 to 5 ppm
CoO. The glass is characterized by a dominant wavelength in the range of
490 nm to 495 nm and an excitation purity in the range of 3% to 11%. The
glass of the invention can be essentially free of Se.
