We present a new invariant, called slope, of a colored link in an integralhomology sphere and use this invariant to complete the signature formula forthe splice of two links. We develop a number of ways of computing the slope anda few vanishing results. Besides, we discuss the concordance invariance of theslope and establish its close relation to the Conway polynomials, on the onehand, and to the Kojima--Yamasaki $\eta$-function (in the univariate case) andCochran invariants, on the other hand.
