Claim:
An ink set for ink jet recording comprising: a black ink; and a plurality of color inks of different colors, wherein the black ink contains a pigment as a coloring material, wherein the color ink having the highest brightness among the plurality of color inks has the highest surface tension among the plurality of color inks, wherein a difference in surface tension between the black ink and the color ink having the highest brightness is 2 dyn/cm (mN/m) or less, wherein the color ink having the highest brightness is a yellow ink, wherein the black ink contains at least one salt selected from the group consisting of (M1) 2 SO 4 , CH 3 COO(M1), Ph-(COO(M1)) n , (M1)NO 3 , (M1)Cl, (M1)Br, (M1)I, (M1) 2 SO 3 , and (M1) 2 CO 3 , where M1 represents an alkali metal, ammonium, or organic ammonium, Ph represents a benzene ring, and n represents 1 or 2, and wherein a surface tension of the yellow ink is lower than the surface tension of the black ink.
