An inkjet ink set includes a nonwhite ink and a white ink. The nonwhite ink contains a nonwhite pigment, a first polysaccharide, glycol ether, and water. The white ink contains a white pigment and water. The nonwhite ink has a first surface tension of at least 30 mN/m and no greater than 40 mN/m. The first surface tension of the nonwhite ink and a second surface tension of the white ink satisfy formula (1) '5 mN/m≤Tc−Tw'. The nonwhite ink has a first viscosity of at least 5.0 mPa·s and no greater than 10.0 mPa·s. The first viscosity of the nonwhite ink and a second viscosity of the white ink satisfy formula (2) “2.0 mPa·s≤Vc−Vw”.
