An ink composition contains a particular anthrapyridone dye and a particular copper phthalocyanine dye. The hue angle in the L*a*b* color system calculated from spectral characteristics of a 1,000-fold diluted solution of the ink composition in water is 270° to 360°. The content of the anthrapyridone dye is higher than the content of the copper phthalocyanine dye.
