A photographic color developing composition includes a color developing agent, an organic antioxidant and at least 0.0005 mol/l of a polyaminopolyphosphonic acid calcium ion sequestering agent that has at least four phosphonic acid (or salt) groups. In addition, the total concentration of lithium and magnesium ions is less than 0.0001 mol/l. This composition can be in working strength or concentrated form (including solids), and has improved stability and reduced precipitates, and in some cases, provides improved yellow dye density.
