  We explore topologically massive gauge theories using the covariant colour
kinematics duality recently introduced by Cheung and Mangan. We show that the
massive bi-adjoint scalar field is simply related to topologically massive
gauge theory by the duality, and that enacting the same duality on the gauge
theory produces topologically massive gravity coupled to a scalar or,
equivalently, an antisymmetric field. We also show that different choices for
the replacement of the colour structure constants with kinematic structure
constants lead to different theories, including a topologically massive
generalisation of Born-Infeld theory.
