"A Colored Version of Tverberg’s Theorem"

Imre Barany and D.G. Larman

February 1990

The main result of this paper is that given n red, n white, and n green points in the plane, it is possible to form n vertex-disjoint triangles Delta₁,...,Delta_n in such a way that the Delta_i has one one red, one white, and one green vertex for every i = 1,...,n and the intersection of these triangles is nonempty.
