An object of the present invention is to provide a method of processing silver halide color paper that ensures (a) promptness such that finished prints can be handed at shop to customers, (b) small installation area for mini-labs, (c) processing solution stability capable of withstanding slack seasons, (d) normal image quality, (e) small replenishment solution amount and (f) inhibition of tar generation and sulfuration phenomenon occurrence. This object can be attained by a concentrated processing composition for color paper which has a concentrated processing composition for bleach replenishment of 3.0 or less in pH containing 0.3 mol/L or more of EDTA.Fe(III) ammonium, 0.3 mol/L or more of a sulfinic acid compound of specified structure and 0.5 mol/L or more of ammonium bromide and a concentrated processing composition for fixative replenishment of 4.0 or more in pH containing 0.7 mol/L of ammonium thiosulfate and 0.4 mol/L or more of ammonium sulfite, and which is used in a processing involving the steps of treatment in a color developer, bleaching treatment and fixing treatment, and a processing method using the concentrated processing composition for color paper.
