摘要： A silver halide color photographic light-sensitive material is provided which comprises a support having thereon a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer, having a spectral sensitivity distribution such that a wavelength weight-averaged in spectral sensitivity distribution of the red-sensitive silver halide emulsion layer is within a range of 595 to 625 nm; a maximum sensitivity wavelength in spectral sensitivity distribution of the blue-sensitive silver halide emulsion layer is within a range of 415 to 470 nm; and a sensitivity of the blue-sensitive silver halide emulsion layer at 480 nm does not exceed 35% of the sensitivity at the maximum sensitivity wavelength. The color photographic material makes it possible to faithfully reproduce the hues such as purple colors and green colors.
