Water base ink set for ink-jet recording

A water base ink set for ink-jet recording comprising:

• a pigment-based black ink containing water, a self-dispersible black pigment, and a water-soluble solvent;
• and
• a dye-based yellow ink containing water, a first water-soluble dye in which a number of counter ion or ions per one molecule is not more than 3 and a hue angle h* is 95° to 105°, and a second water-soluble dye in which a number of counter ion or ions per one molecule is not more than 3 and a hue angle h* is 30° to 70°, wherein:
• a weight ratio of the second water-soluble dye to the first water-soluble dye in the dye-based yellow ink is 0.8 to 5.5%;
• and
• a total content of the first and second water-soluble dyes in the dye-based yellow ink is 1.8 to 5.5% by weight.
