We consider soft-gluon evolution in the colour flow basis. We give explicit expressions for the colour structure of the (one-loop) soft anomalous dimension matrix for an arbitrary number of partons, and we show how the successive exponentiation of classes of large- contributions can be achieved to provide a systematic expansion of the evolution in terms of colour-suppressed contributions.
