A water-based ink for ink-jet recording includes dyes and water. The dyes include a blue dye having a hue angle of 220 to 280; a yellow dye having a hue angle of 70 to 120; and a copper phthalocyanine dye. A mass ratio (C/B) of a content (C) of the copper phthalocyanine dye to a content (B) of the blue dye in an entire amount of the water-based ink is equal to or more than 0.5, and a total content of the dyes in the entire amount of the water-based ink is equal to or more than 6% by mass.
