In this paper we define the chromatic number of a lattice: It is the least number of colors one
needs to color the interiors of the cells of the Voronoi tessellation of a lattice so that no two cells
sharing a facet are of the same color.
We compute the chromatic number of the root lattices, their duals, and of the Leech lattice,
we consider the chromatic number of lattices of Voronoi’s first ...
