Disclosed is a silver halide color photographic light-sensitive material including at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer, and at least one blue-sensitive silver halide emulsion layer on a support, and having an ISO sensitivity of 640 or more, wherein the material exhibits a color saturation evaluation value η, represented by equation (I) below, of −15 dB or more. η=10 log(1/VT) [VT=(⅙)×((62−Y1)2+(62−Y2)2+(62−Y3)2+(62−Y4)2+(62−Y5)2+(62−Y6)2)] (I) In Formula (I), each of Y1 to Y6 is a value obtained by exposing 12 colors of a Macbeth color chart with six exposure amounts, from −1 under to +4 over, measuring the saturation of each resultant color, and averaging the data (chroma values) for a corresponding exposure amount.
A silver halide color photographic light-sensitive material comprising, on a support, a red-sensitive layer unit including at least one red-sensitive silver halide emulsion layer, a green-sensitive layer unit including at least one green-sensitive silver halide emulsion layer, and a blue-sensitive layer unit including at least one blue-sensitive silver halide emulsion layer, said light-sensitive material having an ISO sensitivity of not less than 640, wherein said material exhibits a color saturation evaluation value η, represented by equation (I) below, of not less than −15 dB:
