A single-part, single-phase liquid color developer concentrate for color photographic development having at least one color developing agent of p-phenylenediamine or a derivative or salt thereof, an aqueous solution containing one or more organic solvents in a weight ratio of water to the organic solvent greater than or equal to about 60:40, a molar ratio of [Na<+>]/[K<+>] of at least about 1:2, preferably at least about 2:1, and/or a molar ratio of the organic solvent of Formula (I) to a free base of the p-phenylendiamine or p-phenylendiamine derivative is from about 3:1 to about 30:1 is described. The color developer concentrate is simple to manufacture, stable, compact, easy to use, has good water solubility upon dilution, minimizes mixing errors, and can be used with a very low replenishment rate. A method for processing image-wise exposed photographic color silver halide emulsions using the single-part, single-phase liquid color developer concentrate is also provided.
