In this paper we study those n-color partitions of Agarwal and Andrews, 1987, in whicheach pair of parts has weighted difference equal to −2 Results obtained in this paper for thesepartitions include several combinatorial identities, recurrence relations, generating functions, relationshipswith the divisor function and computer produced tables. By using these partitions an explicit expressionfor the sum of the divisors of odd integers is given. It is shown how these partitions arise in the study ofconjugate and self-conjugate n-color partitions. A combinatorial identity for self-conjugate n-colorpartitions is also obtained. We conclude by posing several open problems in the last section.
