Let HPn,m,k be drawn uniformly from all m-edge, k-uniform, k-partite hypergraphs where each part of the partition is a disjoint copy of [n]. We let HPn,m,k(kappa) be an edge colored version, where we color each edge randomly from one of kappa colors. We show that if kappa = n and m = Kn log n where K is sufficiently large then w.h.p. there is a rainbow colored perfect matching. I. e. a perfect matching in which every edge has a different color. We also show that if n is even and m = Kn log n where K is sufficiently large then w.h.p. there is a rainbow colored Hamilton cycle in G(n,m)((n)). Here G(n,m)((n)) denotes a random edge coloring of G(n, m) with n colors. When n is odd, our proof requires m =omega(n log n) for there to be a rainbow Hamilton cycle.
