  We discuss multichromatic front solutions to the bistable Nagumo lattice
differential equation. Such fronts connect the stable spatially homogeneous
equilibria with spatially heterogeneous $n$-periodic equilibria and hence are
not monotonic like the standard monochromatic fronts. In contrast to the
bichromatic case, our results show that these multichromatic fronts can
disappear and reappear as the diffusion coefficient is increased. In addition,
these multichromatic waves can travel in parameter regimes where the
monochromatic fronts are also free to travel. This leads to intricate collision
processes where an incoming multichromatic wave can reverse its direction and
turn into a monochromatic wave.
