Disclosed is a color photographic element comprising at least five imaging layers including: a first light sensitive silver halide imaging layer having associated therewith a cyan image dye-forming coupler; a second light sensitive silver halide imaging layer having associated therewith a magenta image dye-forming coupler; a third light sensitive silver halide imaging layer having associated therewith a yellow image dye-forming coupler; and a fourth light sensitive silver halide imaging layer having associated therewith a fourth image dye-forming coupler for which the normalized spectral transmission density distribution curve of the dye formed by the fourth image dye-forming coupler upon reaction with color developer has a CIELAB hue angle, hab, from 225 to 310°; and a fifth light sensitive silver halide imaging layer having associated therewith a fifth image dye-forming coupler for which the normalized spectral transmission density distribution curve of the dye formed by the fifth image dye-forming coupler upon reaction with color developer has a CIELAB hue angle, hab, from not less than 355 to not more than 75°. Such an element enables an increase in the color gamut for silver halide imaging.
