A method of forming color photographic images which comprises developing image-exposed photographic silver halide emulsion layer with a primary aromatic amino color developing agent in the presence of a yellow color forming coupler represented by the following general formula (I) ##STR1## wherein X.sub.1 represents a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group or an acyl group; X.sub.2 represents a hydrogen atom, an alkyl group or an aryl group; X.sub.3 represents a hydrogen atom, an alkyl group, an aryl group or an acyl group; Y represents an oxygen atom or a sulfur atom; and Q represents a residue of a yellow color forming coupler, e.g., a yellow coupler in which one hydrogen atom attached to the active methylene group of the coupler is eliminated. These yellow color forming couplers provide yellow color images having superior properties.
