ABSTRACT:
There is disclosed a color developer and a method for processing a silver halide color photographic material using said color developer. The color developer comprises a thiourea compound represented by the formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 each represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted cycloalkylene group, provided that two or more of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 each do not represent a hydrogen atom at the same time; at least one pair of R.sub.1 and R.sub.3, and R.sub.2 and R.sub.4, together may bond to form a nitrogen-containing heterocyclic ring; or at least one pair of R.sub.1 and R.sub.2, and R.sub.3 and R.sub.4, together may bond to form a ring.
