Query: Distributed Colour Reduction Revisited   We give a new, simple distributed algorithm for graph colouring in paths and
cycles. Our algorithm is fast and self-contained, it does not need any globally
consistent orientation, and it reduces the number of colours from $10^{100}$ to
$3$ in three iterations.
