##### Abstract

We explain how existing results (such as categorical ${\mathfrak{s}\mathfrak{l}}_{n}$ actions, associated braid group actions and infinite twists) can be used to define a triply graded link invariant which categorifies the homfly polynomial of links coloured by arbitrary partitions. The construction uses a categorified homfly clasp defined via cabling and infinite twists. We briefly discuss differentials and speculate on related structures.
