For a given n, can we colour the positive integers using precisely n colours in such a way that for any a, the numbers a, 2a, .., na all get different colours? This question is still open in general. I will present a survey of known results and some other problems it leads to. This is joint work with Andrés Caicedo and Thomas Chartier.
